I think this jira is helpful for your question: https://issues.apache.org/jira/browse/FLINK-6328

This is actually an issue for us because we have seen occurrences of false-positive successful
savepoints, perhaps due to S3 latency. Bottom line, we'd like to treat savepoints as insurance
rather than the critical path and would rather they be oblivious to checkpoint management.

management is undergoing some changes in Flink 1.3 (we are on Flink 1.2.0). Any insight is
greatly appreciated.
