> Issue Type: Improvement
> Components: API / DataStream
> Reporter: Rong Rong
> Assignee: Rong Rong
> Priority: Major
>
> 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] in [2]):
> * 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)
> Discussion also extended to introduce configuration such as:
> * MAX_RETRY_COUNT
> * RETRY_FAILURE_POLICY
> REF:
> [1]
