Luke Cwik updated BEAM-14177:
-----------------------------
Description:
The wrong cache key is being used as it has not been namespaced to the state
key.
This was previously being done within StateFetchingIterators but
https://github.com/apache/beam/pull/17121 changed that to use a single shared
key.
The fix is to subcache the cache before passing it into StateFetchingIterators
restoring the prior behavior.
