[jira] [Created] (KUDU-2726) Very large tablets defeat budgeted compaction

Will Berkeley created KUDU-2726:
-----------------------------------

             Summary: Very large tablets defeat budgeted compaction
                 Key: KUDU-2726
                 URL: https://issues.apache.org/jira/browse/KUDU-2726
             Project: Kudu
          Issue Type: Improvement
    Affects Versions: 1.9.0
            Reporter: Will Berkeley


On very large tablets (50GB+), despite being very uncompacted with a large average rowset height, a default budget (128MB) worth of compaction may not reduce average rowset height enough to pass the minimum threshold. Thus the tablet stays uncompacted forever.
