Hyukjin Kwon updated SPARK-40418:
---------------------------------
Component/s: SQL
> Increase default initialNumPartitions to 10
> -------------------------------------------
>
> Key: SPARK-40418
> URL: https://issues.apache.org/jira/browse/SPARK-40418
> Project: Spark
> Issue Type: Improvement
> Components: Spark Core, SQL
> Affects Versions: 3.4.0
> Reporter: Ziqi Liu
> Priority: Major
>
> It's actually an follow-up from SPARK-40211
> The previous default value for initialNumPartitions is 1, which is way too
> small. Change to 10 might be a reasonable value to achieve a middle-ground
> trade-off, and will be beneficial in most cases (unless partition num is too
> small, but in that case either initialNumPartitions and scaleUpFactor won't
> have significant effect)
