> Consider the case using STATE_STORE_CHECKPOINT_FORMAT_VERSION = 1 when a
> batch fails but state files are written. If on the next run, we try to upload
> both a new state file and a file checksum, the file could fail to be uploaded
> but the file checksum is uploaded successfully. This would lead to a
> situation where the old file could be loaded and compared with the new file
> checksum, which would fail the checksum verification. This issue does not
> happen when STATE_STORE_CHECKPOINT_FORMAT_VERSION = 2 since each batch run
> unique ids will be created.
