Subject [jira] [Commented] (CASSANDRA-9282) Warn on unlogged batches
Date Mon, 11 May 2015 13:54:00 GMT


Aleksey Yeschenko commented on CASSANDRA-9282:

FWIW we do that because two keyspaces can have different replication strategies and strategy
options, and there really is no way to merge them further.

It's not a big deal IRL, b/c it's very rare to mix updates to different keyspaces.

> At least until CASSANDRA-8303 is done and we can block them entirely, we should log a
warning when unlogged batches across multiple partition keys are used.  This could either
be done by backporting NoSpamLogger and blindly logging every time, or we could add a threshold
and warn when more than 10 keys are seen.
