[jira] [Updated] (FLINK-11909) Provide default failure/timeout
handling strategy for AsyncIO functions
[ https://issues.apache.org/jira/browse/FLINK-11909?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Rong Rong updated FLINK-11909:
------------------------------
Description:
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)
Discussion also extended to introduce configuration such as:
* MAX_RETRY_COUNT
* RETRY_FAILURE_POLICY
