-----------------------------------------
Summary: use ioprio_set instead of throttling by default
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
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.
