Jeremy Hanna updated CASSANDRA-9946:
------------------------------------
Labels: compaction (was: )
> use ioprio_set on compaction threads by default instead of manually throttling
> ------------------------------------------------------------------------------
>
> Key: CASSANDRA-9946
> URL: https://issues.apache.org/jira/browse/CASSANDRA-9946
> Project: Cassandra
> Issue Type: New Feature
> Components: Core
> Reporter: Jonathan Ellis
> Assignee: Ariel Weisberg
> Labels: compaction
> Fix For: 3.x
>
>
> Compaction throttling works as designed, but it has two drawbacks:
> * it requires manual tuning to choose the "right" value for a given machine
> * it does not allow compaction to "burst" above its limit if there is
> additional i/o capacity available while there are less application requests
> to serve
> Using ioprio_set instead solves both of these problems.
