[GitHub] [doris] zhannngchen opened a new pull request, #15289: [branch-1.1-lts](cherry-pick) delta writer init failed might cause data inconsistency between multiple replicas
zhannngchen opened a new pull request, #15289:

…
In the following case, data inconsistency would happen between multiple replicas
current delta writer only writes a few lines of data (which meas the write() method only called once) writer failed when init()(which is called at the fist time we call write()), and current tablet is recorded in _broken_tablets delta writer closed, and in the close() method, delta writer found it's not inited, treat such case as an empty load, it will try to init again, which would create an empty rowset. tablet sink received the error report in rpc response, marked the replica as failed, but since the quorum replicas are succeed, so the following load commit operation will succeed. FE send publish version task to each be, the one with empty rowset will publish version successfully. We got 2 replica with data and 1 empty replica.
