Apache Spark reassigned SPARK-30427:
------------------------------------
Assignee: (was: Apache Spark)
> Add config item for limiting partition number when calculating statistics
> through File System
> ---------------------------------------------------------------------------------------------
>
> Key: SPARK-30427
> URL: https://issues.apache.org/jira/browse/SPARK-30427
> Project: Spark
> Issue Type: Improvement
> Components: SQL
> Affects Versions: 3.1.0
> Reporter: Hu Fuwang
> Priority: Major
>
> Currently, when spark need to calculate the statistics (eg. sizeInBytes) of
> table partition through file system (eg. HDFS), it does not consider the
> number of partitions. Then if the the number of partitions is huge, it will
> cost much time to calculate the statistics which may be not be that useful.
> It should be reasonable to add a config item to control the limit of
> partition number allowable to calculate statistics through file system.
