https://github.com/apache/flink/pull/5885
Updates:
- 4953ad0 Treat state backend registration meta info as immutable. The new
meta info is instantiated with the reconfigured serializer, instead of
instantiating it with the pre-reconfigured serializer and altering it in there.
- b7a0ed0 Add a new test
`StateBackendTestBase#testStateSerializerReconfiguration` that verifies 1)
state serializers are reconfigured, and 2) state handles actually use the
reconfigured serializer. This is a common test for all state backends.
@StefanRRichter @aljoscha the PR is ready for another review. Could you
have a look?
