Review Comment:
what about batch execution? I think we added the `prepareSnapshotPreBarrier`
mainly for batch execution. Now, batch execution can commit to Iceberg with
checkpointId as `1`, which is a valid checkpoint id. I don't see a correctness
problem with that. but it does feels weird when inspecting the table snapshot
summary.
