Review comment:
There is a NonPartitionedKeyGenerator that you can pass and use for
deletions. Since as a client you are aware of 2 facts a) Either you are using
GLOBAL_INDEX or not b) If this batch is for Deletions, you can configure the
hudi client accordingly with a correct partition generator ->
