# Proposed changes
Issue Number: close #xxx
## Problem summary
In the following case, data inconsistency would happen between multiple
replicas
1. current delta writer only writes a few lines of data (which meas the
`write()` method only called once)
2. writer failed when `init()`(which is called at the fist time we call
`write()`), and current tablet is recorded in `_broken_tablets`
3. 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.
4. 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.
5. FE send publish version task to each be, the one with empty rowset will
publish version successfully.
6. We got 2 replica with data and 1 empty replica.
