e4dd904
…ur (apache#37001)
## Proposed changes
Issue Number: close #xxx
introduced by apache#31268
full clone failure may produce duplicate keys in mow table
the bug would be triggered in the following condition:
1. replica 0 miss version
2. replica 0 try to do full clone from other replicas
3. the full clone failed and the delete bitmap is overrided incorrectly
4. replica 0 try to do incremental clone again and this time the clone
succeed
5. incremental clone can't fix the delete bitmap overrided by previous
failed full clone
6. duplicate key occurred
solution:
for full clone, don't override the delete bitmap, use `merge()` method
instead.
