-----------------------------------------
Component/s: Compaction
> CompactionTask should factor in the disk space that may be used by other
> compactions
> ------------------------------------------------------------------------------------
>
> Key: CASSANDRA-13022
> URL: https://issues.apache.org/jira/browse/CASSANDRA-13022
> Project: Cassandra
> Issue Type: Bug
> Components: Compaction
> Reporter: Jon Haddad
> Priority: Major
>
> It's possible for 2 compactions to be competing for an amount of disk space
> smaller than either one would take up by itself but enough so that the system
> runs out of disk.
> Cassandra should:
> * factor in the estimated disk usage of current running compactions for each
> drive, and subtract that amount from the space available (do not overcommit)
> * detect when several compactions will be competing for space and prioritize
> ones that can complete given the space available.
