             Summary: Release Testing: Verify FLIP-281 Supports speculative execution of sinks
                 Key: FLINK-31005
                 URL: https://issues.apache.org/jira/browse/FLINK-31005
             Project: Flink
          Issue Type: Sub-task
          Components: Runtime / Coordination
            Reporter: Zhu Zhu
             Fix For: 1.17.0


This task aims to verify [FLIP-281 Supports speculative execution of sinks|https://issues.apache.org/jira/browse/FLINK-30725].
The documentation can be found [here|https://nightlies.apache.org/flink/flink-docs-master/docs/deployment/speculative_execution/#enable-sinks-for-speculative-execution] .

Things to verify:
1. If a sink implements the decorative interface {{SupportsConcurrentExecutionAttempts}, Speculative executions can be performed, otherwise not. Sinks to verify includes SinkFunction, OutputFormat and Sink(V2).
2. These built-in sinks supports speculative execution: DiscardingSink, PrintSinkFunction, PrintSink, FileSink, FileSystemOutputFormat, HiveTableSink

If it's hard to construct a case that speculative execution would happen, especially for those built-in sinks, the speculative execution configuration can be tuned to allow it easier to happen, e.g. set {{slow-task-detector.execution-time.baseline-lower-bound}} and {{slow-task-detector.execution-time.baseline-ratio}} to {{0}}.
