--------------------------------------
Summary: 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
Reporter: Jon Haddad
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.
