In unique key with merge on write, we calc delete bitmap of segments in one rowset in DeltaWriter::close_wait, we have to traverse all key and compare to key in pre segment, this logic introduce a lot of bugs and also cost a lot of time. In this pr, we directly do compact all segments of one load, this will make sure that no same key in this load and then we can ignore delete bitmaps between segments. # Proposed changes Issue Number: close #xxx ## Problem summary Describe your changes. ## Checklist(Required) * [ ] Does it affect the original behavior * [ ] Has unit tests been added * [ ] Has document been added or modified * [ ] Does it need to update dependencies * [ ] Is this PR support rollback (If NO, please explain WHY) ## Further comments If this is a relatively large or complex change, kick off the discussion at [d...@doris.apache.org](mailto:d...@doris.apache.org) by explaining why you chose the solution you did and what alternatives you considered, etc... -- This is an automated message from the Apache Git Service.
