-----------------------------------
Summary: Improve rowset compaction policy to consider merging
small DRSs
Key: KUDU-1400
URL: https://issues.apache.org/jira/browse/KUDU-1400
Project: Kudu
Issue Type: Improvement
Reporter: Binglin Chang
We see some small table with light write load generate lot's of small
DRS(~1MB), since those DRSes do not overlap much, they don't get the chance to
be compacted, generating lot of very small files/blocks. So:
# Compaction solution value should consider benefits of merging small DRS
# Every 2 min flushing MRS(small or large) seems suboptimal, maybe flushing
small MRS should have "lower priority" than rowset compaction with higher
solution value?
