---------------------------
Summary: Flink CDC 3.1 breaks operator state compatiblity
Key: FLINK-35464
URL: https://issues.apache.org/jira/browse/FLINK-35464
Project: Flink
Issue Type: Bug
Components: Flink CDC
Affects Versions: cdc-3.1.0
Reporter: yux
Fix For: cdc-3.1.1
Flink CDC 3.1 changed how SchemaRegistry [de]serializes state data, which
causes any checkpoint states saved with earlier version could not be restored
in version 3.1.0.
This could be resolved by adding serialization versioning control logic.
