Will Berkeley reassigned KUDU-1625:
-----------------------------------
Assignee: Will Berkeley
> Schedule compaction on rowsets with high percentage of deleted data
> -------------------------------------------------------------------
>
> Key: KUDU-1625
> URL: https://issues.apache.org/jira/browse/KUDU-1625
> Project: Kudu
> Issue Type: Improvement
> Components: tablet
> Affects Versions: 1.0.0
> Reporter: Todd Lipcon
> Assignee: Will Berkeley
> Priority: Major
>
> Although with KUDU-236 we can now remove rows that were deleted prior to the
> ancient history mark, we don't actively schedule compactions based on deleted
> rows. So, if for example we have a fully compacted table and issue a DELETE
> for every row, the data size actually does not change, because no compactions
> are triggered.
> We need some way to notice the fact that the ratio of deletes to rows is high
> and decide to compact those rowsets.
