Subject [jira] [Commented] (CASSANDRA-7047) TriggerExecutor should group mutations by row key
Date Mon, 21 Apr 2014 16:55:15 GMT


Sergio Bossa commented on CASSANDRA-7047:

If you want to keep your other changes (the grouping of all mutations I mean), I can attach
a patch off your latest one, with just that counters change, straight away tomorrow.

> TriggerExecutor doesn't currently group mutations returned by triggers even if belonging
to the same row key: while harmless per se (at least, I think so), this is definitely a performance
problem, because each mutation is a *cluster* mutation, generating more network traffic, more
disk IO and more index calls (if present).
