> 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.
