---------------------------------
Summary: Provide default failure/timeout handling strategy for
AsyncIO functions
Key: FLINK-11909
URL: https://issues.apache.org/jira/browse/FLINK-11909
Project: Flink
Issue Type: Improvement
Components: API / DataStream
Reporter: Rong Rong
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)
