> After we introduce the native savepoint in flink-1.15, the semantics of the full snapshot changed. "Full snapshot" mainly refers to the newly "Canonical Savepoint", and the previous API of {{StateTTLConfig.Builder#cleanupFullSnapshot}} ([https://nightlies.apache.org/flink/flink-docs-release-1.15/docs/dev/datastream/fault-tolerance/state/#cleanup-in-full-snapshot)] becomes ambiguous. Even we trigger a native savepoint, we cannot cleanup expired data in the generated snapshot.
