dawidwys opened a new pull request #14648: URL: https://github.com/apache/flink/pull/14648
## What is the purpose of the change It is not yet an entirely ready PR. We should agree how we want to pass the information through the `KeyGroupStateHandle` that it is a savepoint. I see two options: 1. Either we add a flag to the `KeyGroupStateHandle` 2. We add `SavepointKeyGroupStateHandle` that extends from `KeyGroupStateHandle`. My concern with the option 2. is that there would be no real difference between the two classes (other than one being a marker for a savepoint). The concern for option 1. is that it requires mingling with the java serialization. ## Verifying this change ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
