------------------------------
Summary: Add userKeySerializer in
RegisteredKeyValueStateBackendMetaInfo V2
Key: FLINK-37569
URL: https://issues.apache.org/jira/browse/FLINK-37569
Project: Flink
Issue Type: Sub-task
Components: Runtime / Checkpointing
Affects Versions: 2.0.0
Reporter: Yue Ma
Fix For: 2.1.0
At present, there is no information about userKeySeriailzer in
org.apache.link.runtime.state.v2.RegisteredKeyValueStateBackendMetaInfo.
If MapState is used and the schema of userKey has changes, StateBackend cannot
determine if it is compatible. So we need to add the information of
userKeySeriailzer in
org.apache.link.runtime.state.v2.RegisteredKeyValueStateBackendMetaInfo
