Marcus Eriksson updated CASSANDRA-7019:
---------------------------------------
Summary: Improve tombstone compactions (was: Major tombstone compaction)
> Improve tombstone compactions
> -----------------------------
>
> Key: CASSANDRA-7019
> URL: https://issues.apache.org/jira/browse/CASSANDRA-7019
> Project: Cassandra
> Issue Type: Improvement
> Reporter: Marcus Eriksson
> Assignee: Marcus Eriksson
> Labels: compaction
> Fix For: 3.0
>
>
> It should be possible to do a "major" tombstone compaction by including all
> sstables, but writing them out 1:1, meaning that if you have 10 sstables
> before, you will have 10 sstables after the compaction with the same data,
> minus all the expired tombstones.
> We could do this in two ways:
> # a nodetool command that includes _all_ sstables
> # once we detect that an sstable has more than x% (20%?) expired tombstones,
> we start one of these compactions, and include all overlapping sstables that
> contain older data.
