Jerry Zheng updated SPARK-55058:
--------------------------------
Description: The {{metadata}} file holds the streaming query ID, and should
be existent if the commit and offset files are non-empty. This file not
existing will result in duplicates and incorrectness downstream if using
DeltaSink which uses the streaming query ID to dedup commits for the same
batch. If the metadata file isn’t there, but the commit and offset files are
there, we should throw an error as the checkpoint is in an inconsistent state.
