Performing maintenance activities on a distributed database requires deep domain knowledge on the internals workings of Cassandra and a lot of custom tooling that is very time consuming. This topic aims to educate on how you can expertly perform the database maintenance operations in autopilot mode at the click of a button and a fraction of the cost of custom development.
