-----------------------------------
Summary: RollingDiskRowSetWriter create rowsets that are bigger
than the target rowset size
Key: KUDU-2725
URL: https://issues.apache.org/jira/browse/KUDU-2725
Project: Kudu
Issue Type: Improvement
Affects Versions: 1.9.0
Reporter: Will Berkeley
The diskrowset writer create rowsets that are bigger than the target rowset
size, with the excess proportional to the number of columns that compress
poorly. For example, modifying loadgen to create a table with 280 columns and
then using the {{--use_random}} flag, I saw rowsets that were in excess of
80MB. This is a problem because the budget for compactions is 128MB, so rowsets
that are that big can never participate in a compaction.
