Chao Sun resolved SPARK-42480. ------------------------------ Fix Version/s: 3.5.0 Resolution: Fixed Issue resolved by pull request 40069 [https://github.com/apache/spark/pull/40069] > 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 > Fix For: 3.5.0 > > > 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. -- This message was sent by Atlassian Jira (v8.20.10#820010) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscr...@spark.apache.org For additional commands, e-mail: issues-h...@spark.apache.org
