--------------------------------
Assignee: Wechar
> Improve the performance of drop partitions
> ------------------------------------------
>
> Key: SPARK-42480
> URL: https://issues.apache.org/jira/browse/SPARK-42480
> Project: Spark
> Issue Type: Improvement
> Components: SQL
> Affects Versions: 3.3.2
> Reporter: Wechar
> Assignee: Wechar
> Priority: Major
>
> Currently to drop the matching partitions, Spark will first get all matching
> Partition objects from Hive metastore, and just use the partition values of
> these Partition objects.
> We can get the matching partition names instead of the partition objects for
> the following reasons:
> 1. we can also get partition values through a partition name (like a=1/b=2)
> 2. the byte size of partition name is much smaller than partition object,
> which will help improve the performance of drop partitions.
