Tupshin Harper updated CASSANDRA-7075:
--------------------------------------
Fix Version/s: 3.0
> Add the ability to automatically distribute your commitlogs across all data
> volumes
> -----------------------------------------------------------------------------------
>
> Key: CASSANDRA-7075
> URL: https://issues.apache.org/jira/browse/CASSANDRA-7075
> Project: Cassandra
> Issue Type: New Feature
> Components: Core
> Reporter: Tupshin Harper
> Priority: Minor
> Labels: performance
> Fix For: 3.0
>
>
> given the prevalance of ssds (no need to separate commitlog and data), and
> improved jbod support, along with CASSANDRA-3578, it seems like we should
> have an option to have one commitlog per data volume, to even the load. i've
> been seeing more and more cases where there isn't an obvious "extra" volume
> to put the commitlog on, and sticking it on only one of the jbodded ssd
> volumes leads to IO imbalance.
