Subject [jira] [Commented] (CASSANDRA-12403) Slow query detecting
Date Thu, 11 Aug 2016 06:50:21 GMT


Stefania commented on CASSANDRA-12403:

Thank you for confirming the suggested implementation.

There were some failures with the tests, mostly unrelated except for [one failure|]
with the new tests. I've fixed the failing test and launched a repeated execution (150 times)
[here|]. I've
also launched the full tests a second time to shake off some of the unrelated failures.

Before committing the patch, I would also like to a have one more person look at it, cc [~JoshuaMcKenzie].

> 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.
