Hi, I'm observing a behavior in Flink 1.20.0 that contradicts the documentation. The JavaDoc for OperatorCoordinator#start() says:
This method is called once at the beginning, before any other methods. However, I see that OperatorCoordinator#resetToCheckpoint() is called even before start(), as part of the object graph creation. The start() method and the JavaDoc in question were introduced in commit 41b6bfa (FLINK-15099). The code that calls resetToCheckpoint() before start() was introduced in commit 52f7b9d (FLINK-16177). Does this mean that this JavaDoc is obsolete and should be corrected? What are the actual guarantees between the order of the calls to these two methods? Thank you. -- Sergei Morozov
