Wenchen Fan reassigned SPARK-32985: ----------------------------------- Assignee: Cheng Su > Decouple bucket filter pruning and bucket table scan > ---------------------------------------------------- > > Key: SPARK-32985 > URL: https://issues.apache.org/jira/browse/SPARK-32985 > Project: Spark > Issue Type: Improvement > Components: SQL > Affects Versions: 3.1.0 > Reporter: Cheng Su > Assignee: Cheng Su > Priority: Minor > > As a followup from discussion in > [https://github.com/apache/spark/pull/29804#discussion_r493100510] . > Currently in data source v1 file scan `FileSourceScanExec`, bucket filter > pruning will only take effect with bucket table scan - > [https://github.com/apache/spark/blob/master/sql/core/src/main/scala/org/apache/spark/sql/execution/DataSourceScanExec.scala#L542] > . However this is unnecessary, as bucket filter pruning can also happen if > we disable bucketed table scan. This help query leverage the benefit from > bucket filter pruning to save CPU/IO to not read unnecessary bucket files, > and do not bound by bucket table scan when the parallelism of tasks is a > concern. -- This message was sent by Atlassian Jira (v8.3.4#803005) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscr...@spark.apache.org For additional commands, e-mail: issues-h...@spark.apache.org
