Todd Lipcon created KUDU-1625: --------------------------------- 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. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
