             Summary: Support custom compression formats for checkpoints (+Upgrade/Compatibility)
                 Key: FLINK-6931
                 URL: https://issues.apache.org/jira/browse/FLINK-6931
             Project: Flink
          Issue Type: Improvement
          Components: State Backends, Checkpointing
            Reporter: Stefan Richter


With FLINK-6773, we introduced optional snappy compression for keyed state in full checkpoints
and savepoints. We should offer users a way to register their own compression formats with
the {{ExecutionConfig}}. For this, we should also have a compatibility story, very similar
to what {{TypeSerializerConfigSnapshot}} doesfor type serializers.
