After reviewing the source code, the batch processing is done asynchronously and eventually uses Future for callbacks.

It is clear that the callback here is null, which will definitely cause an error.

I suggest checking the cluster environment. If batch 1 and 10 to 100 all report errors, there must be an issue with the environment.

The environment should be fine. Using the bulk import program (migration/online-bulk-load at main · tikv/migration · GitHub) can successfully complete the bulk import, and 50,000 per partition is not a problem!
