Dongjoon Hyun updated SPARK-29910:
----------------------------------
Affects Version/s: (was: 3.0.0)
3.1.0
> 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: 3.1.0
> Reporter: Deegue
> Priority: Major
>
> 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`.
