--------------------------------
Summary: TTL state factory should handle extended state descriptors
Key: FLINK-23018
URL: https://issues.apache.org/jira/browse/FLINK-23018
Project: Flink
Issue Type: Bug
Components: Runtime / State Backends
Reporter: Yun Tang
Assignee: Yun Tang
Fix For: 1.14.0
Currently, {{TtlStateFactory}} can only handle fixed type of state descriptors.
As {{ValueStateDescriptor}} is not a final class and user could still extend
it, however, {{TtlStateFactory}} cannot recognize the extending class.
{{TtlStateFactory}} should use {{StateDescriptor#Type}} to check what kinds of
state is.
