You have been asked to administer a Cassandra installation. In this talk, I will take you through basic Cassandra operations from the point of view of a MySQL DBA.
In the beginning, I was simply looking for "where is the equivalent of a .my.cnf?". Over time, that expanded to "how can I be sure this is healthy?", "Why are the users complaining about timeouts connecting?", and "How do I make this cluster replicate into another datacenter?". I will cover all of this and more.
Hopefully, my frustrations will save you some time and pain.
