Too Long; Didn't Read
The <a href="https://www.slideshare.net/planetcassandra/cassandra-summit-2014-cql-under-the-hood-39445761" target="_blank">CQL</a> — Cassandra Query language gives an almost SQL type interface to Apache Cassandra. I have found many times, that many who use this, do not know about some important points of Cassandra that makes it different from SQL databases like Postgres. Same is the case for the operations team, there are some aspects related to storage, GC settings, that many are not aware of. I am not an expert in Cassandra internals and don’t aspire to be if I can avoid it. This is mostly a note to myself, and something which I can ask others to refer to instead of repeating over email a gazillion times. There are a lot of other parts like repair etc which I have left out. The intention here is to make this as short as possible, but if you feel somethings are to be added, please comment.
