[jira] [Created] (SPARK-29910) Add minimum runtime limit to speculation

Deegue created SPARK-29910:
------------------------------

             Summary: Add minimum runtime limit to speculation
                 Key: SPARK-29910
                 URL: https://issues.apache.org/jira/browse/SPARK-29910
             Project: Spark
          Issue Type: Improvement
          Components: SQL
    Affects Versions: 3.0.0
            Reporter: Deegue


The minimum runtime to speculation used to be a fixed value 100ms.  It means tasks finished in seconds will also be speculated and more executors will be required.
To resolve this, we add `spark.speculation.minRuntime` to control the minimum runtime limit for speculation.
We can reduce normal tasks to be speculated by adjusting `spark.speculation.minRuntime`.
