Lots of service providers offer a free tier of their service. The idea is to let you kick their service's tires freely. If you need to go above the free tier at any point, you'll likely stay on the service and pay. In this day and age, most services are online and accessible via an API. Today, we will implement a free tier with Apache APISIX. A naive approach I implemented a free tier in my post Evolving your RESTful APIs, a step-by-step approach, albeit in a very naive way. I copy-pasted the limit-count plugin and added my required logic. function _M.access(conf, ctx)
    core.log.info("ver: ", ctx.conf_version)

    -- no limit if the request is authenticated
    local key = core.request.header(ctx, conf.header)                               #1
    if key then
        local consumer_conf = consumer_mod.plugin("key-auth")                       #2
        if consumer_conf then
            local consumers = lrucache("consumers_key", consumer_conf.conf_version, #3
                    create_consume_cache, consumer_conf)
            local consumer = consumers[key]                                         #4
            if consumer then                                                        #5
                return
            end
        end
    end
-- rest of the logic Get the configured request header value
Get the consumer's key-auth configuration
Get consumers
Get the consumer with the passed API key if they exist
If they exist, bypass the rate-limiting logic The downside of this approach is that the code is now my own. It has evolved since I copied it, and I'm stuck with the version I copied. We can do better with the help of the vars parameter on routes. APISIX route matching APISIX delegates its matching rule to a router. Standard matching parameters include: The URI
The HTTP method. By default, all methods match.
The host
The remote address Most users do match on the URI; a small minority use HTTP methods and the host. However, they are not the only matching parameters. Knowing the rest will bring you into the world of advanced users of APISIX. Let's take a simple example: header-based API versioning. You'd need actually to match a specific HTTP request header. I've already described how to do it previously. In essence, vars is an additional matching criterion that allows the evaluation of APISIX and nginx variables. routes:
  - uri: /*
    upstream_id: 1
    vars: [[ "http_accept", "==", "vnd.ch.frankel.myservice.v1+json" ]] The above route will match if, and only if, the HTTP Accept header is equal to vnd.ch.frankel.myservice.v1+json. You can find the complete list of supported operators in the lua-resty-expr project. APISIX matches routes in a non-specified order by default. If URIs are disjointed, that's not an issue. routes:
  - uri: /*
    upstream_id: 1
    vars: [[ "http_accept", "==", "vnd.ch.frankel.myservice.v1+json" ]]
  - uri: /*
    upstream_id: 2
    vars: [[ "http_accept", "==", "vnd.ch.frankel.myservice.v2+json" ]] Problems arise when URIs are somehow not disjointed. For example, imagine I want to set a default route for unversioned calls. routes:
  - uri: /*
    upstream_id: 1
    vars: [[ "http_accept", "==", "vnd.ch.frankel.myservice.v1+json" ]]
  - uri: /*
    upstream_id: 2
    vars: [[ "http_accept", "==", "vnd.ch.frankel.myservice.v2+json" ]]
  - uri: /*
    upstream_id: 1 We need the third route to be evaluated last. If it's evaluated first, it will match all requests, regardless of their HTTP headers. APISIX offers the priority parameter to order route evaluation. By default, a route's priority is 0. Let's use priority to implement the versioning correctly: routes:
  - uri: /*
    upstream_id: 1
    vars: [[ "http_accept", "==", "vnd.ch.frankel.myservice.v1+json" ]]
    priority: 10                                              #1
  - uri: /*
    upstream_id: 2
    vars: [[ "http_accept", "==", "vnd.ch.frankel.myservice.v2+json" ]]
    priority: 10                                              #1
  - uri: /*
    upstream_id: 1 Evaluated first. The order is not relevant since the URIs are disjointed. Implementing a free tier with matching rules We are now ready to implement our free tier with matching rules. The first route to be evaluated should be the one with authentication and no rate limit: routes:
  - uri: /get
    upstream_id: 1
    vars: [[ "http_apikey", "~~", ".*"]]                      #1
    plugins:
      key-auth: ~                                             #2
    priority: 10                                              #3 Match if the request has an HTTP header named apikey
Authenticate the request
Evaluate first The other route is evaluated afterward. - uri: /get
    upstream_id: 1
    plugins:
      limit-count:                                            #1
        count: 1
        time_window: 60
        rejected_code: 429 Rate limit this route. When you configure APISIX with the above snippets, and it receives a request to /get, it tries to match the first route only if it has an apikey request header: If it has one:

The key-auth plugin kicks in
If it succeeds, APISIX forwards the request to the upstream
If it fails, APISIX returns a 403 HTTP status code


If it has no such request header, it matches the second route with a rate limit. Conclusion A free tier is a must for any API service provider worth its salt. In this post, I've explained how to configure such free tier with Apache APISIX.

If you need to go above the free tier at any point, you'll likely stay on the service and pay. In this day and age, most services are online and accessible via an API. Today, we will implement a free tier with Apache APISIX . Apache APISIX A naive approach I implemented a free tier in my post Evolving your RESTful APIs, a step-by-step approach , albeit in a very naive way. I copy-pasted the limit-count plugin and added my required logic. Evolving your RESTful APIs, a step-by-step approach limit-count function _M.access(conf, ctx)
    core.log.info("ver: ", ctx.conf_version)

    -- no limit if the request is authenticated
    local key = core.request.header(ctx, conf.header)                               #1
    if key then
        local consumer_conf = consumer_mod.plugin("key-auth")                       #2
        if consumer_conf then
            local consumers = lrucache("consumers_key", consumer_conf.conf_version, #3
                    create_consume_cache, consumer_conf)
            local consumer = consumers[key]                                         #4
            if consumer then                                                        #5
                return
            end
        end
    end
-- rest of the logic function _M.access(conf, ctx)
    core.log.info("ver: ", ctx.conf_version)

    -- no limit if the request is authenticated
    local key = core.request.header(ctx, conf.header)                               #1
    if key then
        local consumer_conf = consumer_mod.plugin("key-auth")                       #2
        if consumer_conf then
            local consumers = lrucache("consumers_key", consumer_conf.conf_version, #3
                    create_consume_cache, consumer_conf)
            local consumer = consumers[key]                                         #4
            if consumer then                                                        #5
                return
            end
        end
    end
-- rest of the logic Get the configured request header value Get the consumer's key-auth configuration Get consumers Get the consumer with the passed API key if they exist If they exist, bypass the rate-limiting logic Get the configured request header value Get the consumer's key-auth configuration key-auth Get consumers Get the consumer with the passed API key if they exist If they exist, bypass the rate-limiting logic The downside of this approach is that the code is now my own. It has evolved since I copied it, and I'm stuck with the version I copied. We can do better with the help of the vars parameter on routes. vars APISIX route matching APISIX delegates its matching rule to a router . router Standard matching parameters include: The URI The HTTP method. By default, all methods match. The host The remote address The URI The HTTP method. By default, all methods match. The host The remote address Most users do match on the URI; a small minority use HTTP methods and the host. However, they are not the only matching parameters. Knowing the rest will bring you into the world of advanced users of APISIX. Let's take a simple example: header-based API versioning. You'd need actually to match a specific HTTP request header. I've already described how to do it previously . In essence, vars is an additional matching criterion that allows the evaluation of APISIX and nginx variables. previously vars routes:
  - uri: /*
    upstream_id: 1
    vars: [[ "http_accept", "==", "vnd.ch.frankel.myservice.v1+json" ]] routes:
  - uri: /*
    upstream_id: 1
    vars: [[ "http_accept", "==", "vnd.ch.frankel.myservice.v1+json" ]] The above route will match if, and only if, the HTTP Accept header is equal to vnd.ch.frankel.myservice.v1+json . You can find the complete list of supported operators in the lua-resty-expr project. Accept vnd.ch.frankel.myservice.v1+json lua-resty-expr APISIX matches routes in a non-specified order by default. If URIs are disjointed , that's not an issue. disjointed routes:
  - uri: /*
    upstream_id: 1
    vars: [[ "http_accept", "==", "vnd.ch.frankel.myservice.v1+json" ]]
  - uri: /*
    upstream_id: 2
    vars: [[ "http_accept", "==", "vnd.ch.frankel.myservice.v2+json" ]] routes:
  - uri: /*
    upstream_id: 1
    vars: [[ "http_accept", "==", "vnd.ch.frankel.myservice.v1+json" ]]
  - uri: /*
    upstream_id: 2
    vars: [[ "http_accept", "==", "vnd.ch.frankel.myservice.v2+json" ]] Problems arise when URIs are somehow not disjointed. For example, imagine I want to set a default route for unversioned calls. routes:
  - uri: /*
    upstream_id: 1
    vars: [[ "http_accept", "==", "vnd.ch.frankel.myservice.v1+json" ]]
  - uri: /*
    upstream_id: 2
    vars: [[ "http_accept", "==", "vnd.ch.frankel.myservice.v2+json" ]]
  - uri: /*
    upstream_id: 1 routes:
  - uri: /*
    upstream_id: 1
    vars: [[ "http_accept", "==", "vnd.ch.frankel.myservice.v1+json" ]]
  - uri: /*
    upstream_id: 2
    vars: [[ "http_accept", "==", "vnd.ch.frankel.myservice.v2+json" ]]
  - uri: /*
    upstream_id: 1 We need the third route to be evaluated last. If it's evaluated first, it will match all requests, regardless of their HTTP headers. APISIX offers the priority parameter to order route evaluation. By default, a route's priority is 0. Let's use priority to implement the versioning correctly: priority priority routes:
  - uri: /*
    upstream_id: 1
    vars: [[ "http_accept", "==", "vnd.ch.frankel.myservice.v1+json" ]]
    priority: 10                                              #1
  - uri: /*
    upstream_id: 2
    vars: [[ "http_accept", "==", "vnd.ch.frankel.myservice.v2+json" ]]
    priority: 10                                              #1
  - uri: /*
    upstream_id: 1 routes:
  - uri: /*
    upstream_id: 1
    vars: [[ "http_accept", "==", "vnd.ch.frankel.myservice.v1+json" ]]
    priority: 10                                              #1

  - uri: /*
    upstream_id: 1 Evaluated first. The order is not relevant since the URIs are disjointed. Evaluated first. The order is not relevant since the URIs are disjointed. Implementing a free tier with matching rules We are now ready to implement our free tier with matching rules. The first route to be evaluated should be the one with authentication and no rate limit: routes:
  - uri: /get
    upstream_id: 1
    vars: [[ "http_apikey", "~~", ".*"]]                      #1
    plugins:
      key-auth: ~                                             #2
    priority: 10                                              #3 routes:
  - uri: /get
    upstream_id: 1
    vars: [[ "http_apikey", "~~", ".*"]]                      #1
    plugins:
      key-auth: ~                                             #2
    priority: 10                                              #3 Match if the request has an HTTP header named apikey Authenticate the request Evaluate first Match if the request has an HTTP header named apikey apikey Authenticate the request Evaluate first The other route is evaluated afterward. - uri: /get
    upstream_id: 1
    plugins:
      limit-count:                                            #1
        count: 1
        time_window: 60
        rejected_code: 429 - uri: /get
    upstream_id: 1
    plugins:
      limit-count:                                            #1
        count: 1
        time_window: 60
        rejected_code: 429 Rate limit this route. Rate limit this route. When you configure APISIX with the above snippets, and it receives a request to /get , it tries to match the first route only if it has an apikey request header: /get only apikey If it has one:

The key-auth plugin kicks in
If it succeeds, APISIX forwards the request to the upstream
If it fails, APISIX returns a 403 HTTP status code If it has no such request header, it matches the second route with a rate limit. If it has one: The key-auth plugin kicks in
If it succeeds, APISIX forwards the request to the upstream
If it fails, APISIX returns a 403 HTTP status code The key-auth plugin kicks in If it succeeds, APISIX forwards the request to the upstream If it fails, APISIX returns a 403 HTTP status code The key-auth plugin kicks in key-auth If it succeeds, APISIX forwards the request to the upstream If it fails, APISIX returns a 403 HTTP status code If it has no such request header, it matches the second route with a rate limit. Conclusion A free tier is a must for any API service provider worth its salt. In this post, I've explained how to configure such free tier with Apache APISIX.

Implementing a Free Tier API: Route Matching with Apache APISIX

While Bitcoin has gained greater institutional acceptance with the recent ETF launches in the US, it is still not a pure institutional asset, and it is not a pure commodity like gold. It is so much more: secure, decentralized, and programmable value. Zulu Network believes that Bitcoin can be so much more. The Bitcoin Ecosystem is ready to evolve by adding BitFi (Bitcoin Native DeFi), integrating existing infrastructure, and advanced programmability to take Bitcoin from a store of value into a new economy with native yield, exciting innovations, and sophisticated DeFi applications. Zulu Network is the first Bitcoin Layer 2 with a Dual-Layer architecture (L2+L3). ZuluPrime L2 is EVM compatible for Bitcoin scaling and BitFi (Bitcoin DeFi); ZuluNexus L3 offers UTXO programmability, a unique solution to continuously support Bitcoin native innovation, making transactions cheaper, fast, extendable, and programmable. Zulu’s other innovations also include the first Bitcoin decentralized bridge (with a working demo coming in the next couple of weeks) and its unique hybrid PoS / PoW mining design. BitFi has the potential to reshape the financial industry and offer individuals greater control over their financial assets. However, its scalability capacity is currently limited. There is clearly massive demand, but poor infrastructure and limitations for mass adoption, like scalability issues, to foster new Bitcoin native format innovations. Zulu Network is building a new infrastructure to solve these limitations with a programmable, extendable, and innovative new approach to the Bitcoin Ecosystem. Zulu wants to unlock the Bitcoin Economy for all developers and users. Zulu Network’s Ground-Breaking Architecture Zulu Network’s unique Two-Tier architecture (L2+L3) aims to move the Bitcoin Network forward with a new infrastructure that solves the limitations of the current Bitcoin ecosystem, such as big demand but poor infrastructure, scalability issues, and lack of native innovations that limit the potential for mass adoption. Zulu’s Bitcoin Layer 2 solution offers a unique two-tiered architecture, supporting both EVM and UTXO, paving the way for revolutionary advancements within the Bitcoin ecosystem: ZuluPrime L2 is EVM compatible, for Bitcoin scaling and BitFi (Bitcoin DeFi).

You can jump to any chapter in this book . RUBBER TIRES FOR TRACTION ENGINES. here RUBBER TIRES FOR TRACTION ENGINES. When it was first discovered that a smooth-faced driving wheel, running on a smooth-faced rail, would "bite," the era of iron railways and locomotive engines may be said to have fairly commenced. The correction of a single radical error was, in this case, the dawn of a new system of travel, so extensive in its growth and marvelous in its results, that even the wildest dreamer could not, at that time, have imagined the consequences of so simple a discovery. A popular and somewhat similar error regarding the bite of wheels on rough and uneven surfaces, has also prevailed. We say popular error, because engineers have not shared it, and it has obtained, to any notable extent, only among those unfamiliar with mechanical science. The error in question is, that hard-surfaced wheels will not bite on a moderately rough surface, sufficiently to give an efficient tractile power. It seems strange that this error should have diffused itself very extensively, when it is remembered that a certain degree of roughness is essential to frictional resistance. The smoothness of the ordinary railway track is roughness compared to that of an oiled or unctuous metallic surface; and it has been amply demonstrated that the resistance of friction, of two bearing surfaces depends, not upon their extent, but upon the pressure with which they are forced together. A traction wheel, of given weight, resting upon two square inches of hard earth or rock, would develop the same tractile power as though it had a bearing surface of two square feet of similar material. On very rough and stony ways, however, another element practically of no importance on moderately rough ways, like a macadam surface or a concrete road, where the prominences are nearly of uniform hight, and so near together as to admit between their summits only very small arcs of the circumference of the wheel; comes into action. This element is the constantly recurring lifting of the superincumbent weight of the machine. Even this would not result in loss of power, could the power developed in falling be wholly applied to useful work in the direction of the advance of the engine. The fact is, however, that it is not so applied, and in any method of propulsion at present known to engineering science, cannot be so applied. Above a certain point where friction enough is developed to prevent slip, the more uneven the road surface is, the greater the power demanded for the propulsion of the locomotive. And this will hold good for both hard and soft-tired wheels. What then is the advantage, if any, of rubber-tired wheels? The advantages claimed may be enumerated as follows: increased tractile power, with a given weight, secured without damage to roadways; ease of carriage to the supported machinery, whereby it—the machinery—is saved from stress and wear; and economy of the power, expended in moving the extra weight required by rigid-tired wheels, to secure the required frictional resistance. The last-mentioned claim depends upon the first, and must stand or fall with it. The saving of roadway, ease of carriage, and its favorable result upon the machinery, are generally conceded. A denial of the first claim has been made, by those interested in the manufacture of rigid-tired traction engines and others, in so far as the rubber tires are employed on comparatively smooth surfaces; although the increased tractile power on quite pavements and roads is acknowledged. rough This denial is based upon results of experiments performed on the streets of Rochester, England, between the 9th October and the 2nd November, 1870, by a committee of the Royal Engineers (British Army), with a view to determine accurately the point in question. Care was taken to make the circumstances, under which the trials took place, exactly alike for both the rubber and the iron tires. The experiments were performed with an Aveling and Porter six-horse power road engine, built in the Royal Engineers' establishment. The weight of the engine, without rubber tires, was 11,225 pounds; with rubber tires, it weighed 12,025 pounds. Without rubber tires it drew 2.813 times its own weight up a gradient of 1 in [missing]; with rubber tires, it drew up the same incline 2.763 times the weight of engine, with the weight of rubber tires added; showing that, although it drew a little over 2,200 pounds more than it could do without the rubber tires, the increase of traction was only that which might be expected from the additional weight. It is claimed, moreover, that the additional traction power and superior ease of carriage on rough roads, secured with rubber tires, is dearly bought at the very great increase in cost, of an engine fitted with them, over one not so fitted. This is a point we regard as not fully settled, though it will not long remain in doubt. There are enough of both types of wheels now in use to soon answer practically any question there may be of durability (upon which the point of economy hinges), so far as the interest on the increased cost due to rubber tires, is offset against the greater wear and tear of iron rimmed wheels. It is stated, on good authority that a rubber tired engine, started at work in Aberdeen, Scotland, wore out its tires between April and September, inclusive, and when it is taken into consideration, that the cost of these tires is about half that of other engines, made with solid iron rimmed driving wheels, it will be seen that, unless very much greater durability than this can be shown for the rubber, the advantages of such tires are very nearly, if not more than, balanced by their disadvantages. The fact that one set of tires wore out so soon does not prove a rule. There may have been causes at work which do not affect such tires generally, and it would be, we think, quite premature to form favorable or unfavorable judgment, of relative economy from such data as have been yet furnished. The difference in the current expenses of running the two most prominent types of engines, with hard and soft tires, now in use, does not affect the question of rubber tires, unless it can be shown that these tires necessitate, , such a form of engine as requires a greater consumption of fuel, and greater cost of attendance, to perform a given amount of work. per se About HackerNoon Book Series: We bring you the most important technical, scientific, and insightful public domain books.

RUBBER TIRES FOR TRACTION ENGINES

Products like Amazon RDS for are fine for smaller deployments, but scaling PostgreSQL is a different story. Once the project grows to many terabytes, these managed databases get slow and expensive, making data management much more complex. PostgreSQL Performance suffers once tables reach billions of rows, and while , the data will carry on growing. Without proper data management, developers can only watch their disks (and bills) increase in size. it there are ways to improve But not anymore. Today, we’re happy to announce the General Availability of Tiered Storage, a multi-tiered storage architecture engineered to enable infinite, low-cost scalability for your time series and analytical databases in the Timescale platform. You can now store your older, infrequently accessed data in a low-cost storage tier while still being able to access it—without ever sacrificing performance for your frequently accessed data. This is what happens when you insert data into a Timescale time-series database with our new multi-tiered storage backend: Your most recent data will be written into a optimized for fast queries and high ingests. high-performance storage tier Once you don’t access that data frequently, you can automatically tier it to a by setting up a tiering policy. The data in the low-cost storage tier remains fully queryable within your database, and there’s no limit to the amount of data you can store—up to hundreds of TBs or more. lower-cost object storage tier Our low-cost storage tier has a flat price of $0.021 per GB/month for data—cheaper than Amazon S3. Developers need a cheap way to scale their large PostgreSQL databases in without compromising performance. While object stores are amazingly scalable and affordable, they are not the fastest, and developers need to get millisecond query responses for their applications. AWS also However, once data becomes older and rarely accessed, real-time performance is often not as essential. Developers still need to be able to access this historical data for ad hoc queries, data analysis, or regulatory compliance, but they can assume some latency for these types of queries. Now, what developers want is the ability to store this historical data as affordably and efficiently as possible. This new Tiered Storage architecture frees developers from choosing between storage costs and performance trade-offs for real-time applications. By keeping their recent and frequently accessed data in the high-performance tier, they’ll leverage the millisecond query speed and ingestion capabilities of Timescale, and by tiering their older data, they can keep as many TBs as they need in their PostgreSQL databases for less. PostgreSQL Data Management With Tiered Storage: What You Need to Know Timescale’s Tiered Storage architecture leverages the flexibility of PostgreSQL and for effective data management. When creating a hypertable, it can now seamlessly stretch across both storage tiers; , Timescale seamlessly figures out what storage tiers to access to generate the response, boosting performance for your most recent data and lowering storage costs for older data. There’s no extra charge per query or data read and no hidden fees, enabling straightforward, cost-effective data management. hypertables when you run a query This storage architecture also eliminates any storage limitations in Timescale services: since our low-cost storage tier is infinite, you can store as many TBs as you’d like. For example, we’re leveraging Tiered Storage internally to store the huge Timescale database powering our Insights product. This Insights database is constantly collecting and analyzing query statistics from across our customer fleet, and it’s exceeded 350 TB today and is growing quickly. From those 350 TB, 250 TB are tiered to low-cost storage. Let’s do the math: We store 5 TB in our high-performance storage tier Of course, we have compression enabled, and we’re getting compression ratios of 20x—meaning that what was originally 100 TB of Postgres data now fits in a 5 TB disk thanks to compression (!) after compression. The remaining 250 TB of data are stored in the low-cost storage tier. This tiering happens automatically once data hits a certain age, which currently is several weeks old. Our customers with large deployments are also already making use of Tiered Storage: "We perform a lot of analysis on market data, and the sheer volume of data we need to store makes a normal disk-based database solution unfeasible (it's just too expensive). Timescale’s Tiered Storage seamlessly allows us to move large volumes of data to the object storage layer. This is a great solution to store large volumes of historical data and perform post-analysis. Without this, we'd be forced to develop a solution in-house." - Chief Technology Officer at a Proprietary Digital Assets Trading Company Simplicity is the key feature of Tiered Storage. To move your data from the high-performance tier to the low-cost object tier, all you need to do is use our to define policies to tier your data as it ages on a particular hypertable. Data tiering policies work on a chunk basis (the policy will tier complete chunks once they reach the age defined by the policy). There’s no need for any ETL (extract-transform-load) processes or infrastructure changes. simple API Timescale hypertables are PostgreSQL tables automatically partitioned by time. Those partitions are called chunks. Chunks are the unit of user-defined policies in Timescale: for example, when you define a data retention policy, you’ll be deleting entire partitions (chunks), and when you move data between storage tiers, you’ll be moving entire chunks. This is a very convenient way to manage data from a resource-utilization and developer experience perspective. Editor's Note: For example, this policy would move all data older than one month to object storage in your hypertable: events SELECT add_tiering_policy('events', INTERVAL '1 month'); That’s all you need! Everything else happens automatically, including intelligent query planning that only executes any SQL queries on the appropriate tier. To drop data currently stored in the low-cost storage tier, you can define a data retention policy so data is deleted automatically after a certain period (e.g., after five years). . You can also manually delete specific chunks Also, if you want to “move back” a particular chunk from the low-cost storage tier to the high-performance tier ( ), you can easily “untier” it. for example, if you need to backfill or update data -- Untier a particular chunk
CALL untier_chunk('_hyper_1_1_chunk'); You can track how much data has been tiered (and how much it will cost at the end of the month) in the Timescale console: And speaking of billing estimations… How much can I save with Tiered Storage? Our high-performance storage tier has an effective price of $0.177 per GB/month of data (considering the expected compression rate we see across our fleet).  This is now joined by a low-cost storage layer with a flat fee of $0.021 per GB/month of data, with the same price across all cloud regions. after compression When tiering data, you will , not for the queries executed or the amount of data scanned: this is truly a flat price. Our goal with this pricing structure was to provide a transparent, unambiguous, and simple way to calculate the total data storage cost, making it easier to manage your data. only pay for the data you store As a quick example, let’s say you have a hypertable with 5.2 TB of storage, with recent hypertable chunks and other Postgres tables taking up approximately 200 GB and about 5 TB of hypertable data older than a month. You do not access or query this older data frequently, meaning you don’t need it for the daily operations of your application. Still, you’d like to keep it accessible in your database for ad hoc queries or compliance requirements (we see many such cases among our customers). As a cost-effective data management strategy, you can tier all chunks older than a month to the low-cost tier and decrease the cost of storing that 5 TB of data from around $478/month to around $105/month, ( a 78% decrease in your storage bill. For this estimation, we assume you enabled compression for your hypertable and consider the median overall compression in all Timescale services). The savings will increase alongside your data: when moving multiple terabytes to this low-cost tier, your storage bill will decrease from thousands of dollars to a few hundred. The following reference table illustrates how affordable our low-cost storage tier actually is. You get the point! The savings’ multiplication effect of Tiered Storage There is one more thing that makes Tiered Storage even more amazing: when you keep data in the low-cost storage tier, you pay for this data only once, independently of if you have a high-availability replica or read replicas running in your service. The same applies to forks. In Timescale, you can create copies of your primary database (we call them forks) by clicking one button from the UI, for example, for running tests or creating dev environments. When creating one (or more) forks, . If you decide to tier more data that’s not in the primary, you will pay to store it in the low-cost tier, but you will still benefit from substantial savings by moving it from the high-performance tier of the fork to the cheaper tier. you won’t be billed for data shared with the primary in the low-cost storage To make this crystal clear, let’s roll out an example. Imagine that you have a primary service with 6.5 TB of data and that you also have set: A high-availability replica to significantly reduce the risk of downtime and data loss due to failures A read replica to serve your read queries and allow the primary to dedicate itself fully to writes A fork of that service for development and testing purposes From a billing perspective, if you kept the 6.5 TB of data in your primary service in the high-performance storage tier, you would see reflected [6.5 TB x 4] in your storage bill to account for the two replicas, the fork, and the primary service—26 TB in total. Assuming our median compression rate, this would be costly: around $4,602 /month. But what happens if your application needs to actively access only the most recent 500 GB of data? You could tier 6 TB to low-cost storage and only keep 500 GB on your high-performance storage tier. And since you only pay for the data in your low-cost storage tier once, this is how your new storage bill would look like: [500 GB x 4] = 2 TB in high-performance storage (instead of 26 TB) [6 TB x 1] in the low-cost storage tier The above storage bill would come up to approximately $480 /month: This is the savings' multiplication effect of Tiered Storage. Especially if you’re running replicas or forks, it is a great idea to take advantage of the low-cost storage tier—the savings you’ll see in your overall bill will be very significant. you would save over $4,000/month! Our Tiered Storage Journey We released an early version of our Tiered Storage functionality in the Timescale platform as Early Access in March. After many improvements, it has now reached General Availability. Since its first release, we have worked hard to make Tiered Storage stable, reliable, and faster. We also thought long and hard about our pricing model, iterating consistently over multiple ways to price our low-cost storage tier. Finally, we leaned towards the simplest: a flat rate over the data volume pre-compression. We’ve already mentioned how we valued simple and predictable pricing, but it was also important for us to provide a price per GB/month as low as possible. Our price landed at $0.021—as a comparison, storing files on Amazon S3 costs . $0.023 per GB/month Personally, I (Yannis) must admit that after leading teams building cloud-native solutions for more than a decade, I still have to go back and occasionally recheck multiple rate tables on various cloud pricing pages, especially looking for extra fees, every time that I want to compute the total costs for our services accurately. At Timescale, we believe that you should not have to build a complicated spreadsheet to be able to run a database service or make informed choices about storage layers. Our commitment to making developers’ lives easier led us to the flat rate of $0.021 per GB/month—no guesswork, hidden costs, or charges per query or data reads. means the data volume before applying Timescale compression. For example, due to Timescale compression, a 500 GB volume in the high-performance storage tier might end up needing only 50 GB of disk space once compressed. If you decided to tier this data to low-cost storage, your bill would be calculated over the original 500 GB volume, as in [500 GB * $0.021] per month. Data volume pre-compression How Tiered Storage Works: Behind the Scenes All data inserted into Timescale is initially written into our high-performance storage layer. Using faster disks for your most recent data will bring top insert and query performance for your most recent values, a usage pattern that fits the needs of data-intensive applications. On the contrary, the low-cost storage tier is an object store built on Amazon S3. This object store is much more than an external bucket to archive your data, though: it’s an integral part of your database. When you move data to this object storage tier, your database will remain fully aware of all the semantics and metadata, and you can keep querying as usual with standard SQL (albeit with slower performance). Behind the scenes, we’re storing the data in a compressed columnar format (specifically, ). When data is tiered, chunks stored in Timescale’s native internal database format (typically in our ) are asynchronously converted to Parquet format and stored in the underlying S3 object. We’ve built several mechanisms to ensure that the tiered chunks are durably stored in the low-cost storage tier before transactionally removing them from the high-performance tier. Apache Parquet native columnar compression When you run your SQL query, it will transparently pull data from the high-performance storage tier, the object storage tier, or both, as required. When we say transparent, we mean transparent: Timescale supports arbitrarily complex queries across its standard and tiered data, including complex predicates, JOINs, CTEs, windowing, hyperfunctions, and more. In the example query below (with an clause), you can see how the query plan includes a when the database is accessing data from the object storage tier. In this example, and are standard Postgres tables (residing only in high-performance storage), while is a hypertable that stretches across both storage tiers.  When executing this query against the hypertable, three of its chunks were read from standard storage, and five chunks were read from object storage.

Powered by GPT-4: Unlike some other chatbots, Bing also supports visual queries and can provide visual answers.

Bing is free to use. So, if you’re looking for a no-cost alternative to ChatGPT, Bing offers a compelling case. 3. Google Bard There are now a lot of new AI conversational apps, but Google Bard an excellent alternative to ChatGPT after Microsoft's Bing Chat. It uses LAMDA (Language Model for Dialogue Applications) to have deep and long talks with users. Why Try Google Bard as an Alternative to ChatGPT Google Bard presents itself as an intriguing alternative to ChatGPT, particularly for those who are already invested in Google's ecosystem of products and services. Google Bard is also meant to be very good at understanding context and producing text that makes sense and is relevant to the context. Key Features: : Unlike other alternatives, Bard accepts both text and image inputs, making it a multi-modal chatbot. This opens doors to diverse use cases, from visual searches to image-based Q&As. Text and Image Uploads : Google's extensive database is a treasure trove of information. Bard taps into this to deliver answers that are accurate and incredibly exhaustive. Real-time Research : Bard relies on Google's next-gen PaLM 2 language and conversational model, which offers a more refined conversational experience compared to its predecessors. PaLM 2-Powered : Whether you're a coder or a content creator, Bard's export options are a boon. You can export your interactions to Google Docs or Colab, enhancing workflow efficiency. Export Capabilities : Bard's language capabilities are not confined to English. It supports multiple languages, making it an ideal tool for global users. Multilingual Support Pricing: As of now, Google Bard is free of cost since it is an experimental project. Google has not disclosed any future pricing plans, making it an attractive option for budget-conscious users. 4. Claude AI The fourth alternative to ChatGPT that has gained a lot of users in the past month is Claude AI, developed by Anthropic. With enhanced features and capabilities, Claude 2 takes the user experience to a new level. The company, which has received support from Google, positions itself as a direct competitor to OpenAI. Claude does not traditionally use the LLM model. The product utilizes unique AI techniques, referred to as "proprietary," which encompass a neural network, training data, and other undisclosed components. Why Try Claude AI as an Alternative to ChatGPT ClaudeAI is cool and does some things better than ChatGPT. First, you can add files like Word or PDFs. Claude reads them and then talks to you about them. This is something ChatGPT can't do. You can ask Claude questions about the file you uploaded, and it understands what you're asking. Another cool thing is Claude can handle a lot of words. You can chat about many things at once, and it will not forget what it said earlier. It's like talking to a friend who listens. That's because Claude uses 100K tokens, way more than ChatGPT's 8K. Claude knows things that happened up to early 2023, so it has fresher info than ChatGPT. If you want to know about new phones or events, Claude is better. But be careful with links. Claude tries to tell you what a website says, but sometimes it gets wrong. So don't trust it too much for this. Still, Claude has a lot going for it, and it is a good option if you need to upload files or want more recent information. Key Features: : Claude's got a 100k context window. What does that mean? It means it remembers a lot of what you said, so you don't have to keep repeating yourself. Big Chat Window : You can load a whole library of books into Claude. So, if you're a book lover, you and Claude will get along just fine. Book Smart : You can even send PDF files to Claude. I'll read them and chat about it with you. File Uploads : Claude is designed to be super safe to use. That's a big deal if you're worried about that kind of thing. Safe and Sound Pricing: Guess what? Claude is free right now if you're in certain countries. But they also have some plans where you pay based on how much you chat. It's cheaper than GPT-4, so that's something to consider if you're watching your wallet. 5. Poe AI Poe is a popular chatbot website that uses artificial intelligence to answer questions as quickly as possible. This unique Quora product is built on OpenAI GPT and Claude-version 1.2. Why Try Poe AI as an Alternative to ChatGPT Poe AI is the brainchild of Quora's CEO, Adam D'Angelo. His aim? To make bots easy for all to use. Poe AI offers something different in a busy field of bots like Google Bard and Bing AI. However, it's not free right now as you can only type 2 to 3 messages per day, and it costs $19/month, but it has some good reviews. The reason why it ranks so low on our list is that it lacks a lot of features that Chatsonic or Microsoft Bing AI Chat provides. Key Features: : Poe offers access to various bots like ChatGPT, GPT-4, Claude Plus, and Claude Instant, all in one interface. Multiple Bots in One App : Poe's mobile app makes it easy to chat on the go, a feature that many users find convenient compared to web-only interfaces.

It's a decent deal if you plan to use bots a lot. $19.99 a month 6. Jasper Chat Jasper is a powerful tool that makes different kinds of content using AI.

There are several worthy ChatGPT alternatives in the market. But, based on functionality, ease of use, and value for money, Chatsonic by Writesonic and Jasper stand out as top contenders. Everything I Liked : Writesonic doesn’t just limit itself to chat functionalities; it also offers a robust set of tools for content creation, from blog posts and articles to social media updates. Rich Feature Set : Writesonic’s underlying language model has been trained extensively, ensuring that the text generated is coherent, relevant, and, most importantly, human-like. High-Quality Text Generation : With a clean, intuitive UI, Writesonic makes it easy, even for those who are not tech savvy, to navigate through its numerous features.

Pricing Flexibility Honorable Mention: Jasper If cost were not a factor, Jasper would be a strong contender for the top spot.
