[FLINK-17376] Remove deprecated state access methods

• Type: Improvement
• Status: Closed
• Priority: Critical
• Resolution: Fixed
• Fix Version/s: 1.11.0
• Component/s: API / DataStream
• Labels: pull-request-available starter

Release Note

We removed deprecated state access methods `RuntimeContext.getFoldingState(...)`, `OperatorStateStore.getSerializableListState(...)`, and `OperatorStateStore.getOperatorState(...)`. This means that some code that was compiled against Flink 1.10 will not work with a Flink 1.11 cluster. An example of this is our Kafka connector which internally used `OperatorStateStore.getSerializableListState`.

Description

Some methods for state access in the DataStream API are deprecated for three years (yes, indeed!) and are still around and confusing users. We should finally remove them.

The methods are

• RuntimeContext.getFoldingState(...)
• OperatorStateStore.getSerializableListState(...)
• OperatorStateStore.getOperatorState(...)
