lincoln-lil opened a new pull request, #20051:
URL: https://github.com/apache/flink/pull/20051
## What is the purpose of the change
In stream processing, records will be deleted when exceed state ttl (if
configured), and when the corresponding record's update arrives again, the
operator may not be able to handle it properly, we need a unified error
handling mechanism to
handle this situation, instead of each stateful operator currently handling
its own.
TODO the document will be updated if no comment on the option description.
## Brief change log
* add 'table.exec.state-stale.error-handling' to ExecutionConfigOptions
* add utility class `ErrorHandlingUtil` for unified state stale error
handling
* apply the state stale error handling logic to related stateful streaming
operators
* update existing tests to ensure error handling is covered
