Todd Lipcon created KUDU-1625:

             Summary: Schedule compaction on rowsets with high percentage of 
deleted data
                 Key: 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 

We need some way to notice the fact that the ratio of deletes to rows is high 
and decide to compact those rowsets.
