[jira] [Created] (FLINK-29766) Speculative execution supports hybrid shuffle mode.

Weijie Guo created FLINK-29766:
----------------------------------

             Summary: Speculative execution supports hybrid shuffle mode.
                 Key: FLINK-29766
                 URL: https://issues.apache.org/jira/browse/FLINK-29766
             Project: Flink
          Issue Type: Improvement
          Components: Runtime / Coordination
    Affects Versions: 1.17.0
            Reporter: Weijie Guo


Speculation execution is a very important piece for large-scale batch jobs, but it can only work in the BLOCKING shuffle mode, I propose to also support this feature for HYBRID shuffle mode to combine the power of hybrid shuffle and speculative execution.
