Yun Tang updated FLINK-23018:
-----------------------------
Description:
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 kind of
state is.
