Subject [jira] [Updated] (CASSANDRA-10540) RangeAwareCompaction
Date Thu, 22 Oct 2015 10:21:27 GMT

     [ https://issues.apache.org/jira/browse/CASSANDRA-10540?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Marcus Eriksson updated CASSANDRA-10540:
----------------------------------------
    Description: 
Broken out from CASSANDRA-6696, we should split sstables based on ranges during compaction.

Requirements;
* dont create tiny sstables - keep them bunched together until a single vnode is big enough
(configurable how big that is)
* make it possible to run existing compaction strategies on the per-range sstables

We should probably add a global compaction strategy parameter that states whether this should
be enabled or not.

My wip-branch is here (broken out from 6696, probably does not build); https://github.com/krummas/cassandra/commits/marcuse/vnodeawarecompaction
- naming is wrong - we should split based on local ranges even without vnodes
