acelyc111 opened a new issue #3687:
URL: https://github.com/apache/incubator-doris/issues/3687
**Describe the bug**
When a tablet cumulate many rowsets and is picked to do cumulative
compaction for the first time, cumulative compaction will be skipped,
cumulative point will move from -1 to the last version + 1 of the rowset, and
will also influence the next base compaction of the rowset (because too many
rowsets take part in base compaction).
**To Reproduce**
Steps to reproduce the behavior:
1. Adjust some base compaction and cumulative configs to make compaction
execute very slow(i.e. set base/cumulative_compaction_check_interval_seconds to
a large number).
2. Load some data to generate many rowsets on a tablet.
3. Some tablet will be picked to do cumulative compaction, but failed to do
compaction.
**Expected behavior**
Cumulative point is -1 when a tablet has been do any compaction, when it was
picked to do cumulative compaction, the first
config::max_cumulative_compaction_num_singleton_deltas
rowsets should be picked to do cumulative compaction.
