Subject [jira] [Created] (CASSANDRA-9946) use ioprio_set instead of throttling by default
Date Fri, 31 Jul 2015 00:53:04 GMT
Jonathan Ellis created CASSANDRA-9946:

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