> Currently Flink AsyncIO by default fails the entire job when async function invoke fails
[1]. It would be nice to have some default Async IO failure/timeout handling strategy, or
opens up some APIs for AsyncFunction timeout method to interact with the AsyncWaitOperator.
For example (quote [~suez1224]) :
> * FAIL_OPERATOR (default & current behavior)
> * FIX_INTERVAL_RETRY (retry with configurable fixed interval up to N times)
> * EXP_BACKOFF_RETRY (retry with exponential backoff up to N times)
