Alex Petrov commented on CASSANDRA-12403:
-----------------------------------------
Java Driver has a {{QueryLogger.SLOW}} that might be helpful in such
circumstances. The big advantage of having it on client side is that you can
also catch queries that are caused by slowness of client and network latencies
between client and the server.

> Hello,
> In cassandra production environment, users sometimes build anti-pattern
> tables and throw queries in inefficient manners.
> So I would like to suggest a feature that enables to log slow query.
> The feature can help cassandra operators to identify bad query patterns.
> Then operators can give advices about queries and data model to users who
> don't know cassandra so much.
> This ticket is related to CASSANDRA-6226, and I focus on detecting bad query
> patterns, not aborting them.
