---------------------------------
Summary: 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
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.
