Felix Cheung updated SPARK-22637: --------------------------------- Target Version/s: 2.2.2, 2.3.0 (was: 2.3.0) > CatalogImpl.refresh() has quadratic complexity for a view > --------------------------------------------------------- > > Key: SPARK-22637 > URL: https://issues.apache.org/jira/browse/SPARK-22637 > Project: Spark > Issue Type: Bug > Components: SQL > Affects Versions: 2.2.0 > Reporter: Herman van Hovell > Assignee: Herman van Hovell > Priority: Minor > Fix For: 2.2.2, 2.3.0 > > > {{org.apache.spark.sql.internal.CatalogImpl.refreshTable}} uses > {{foreach(..)}} to refresh all tables in a view. This traverses all nodes in > the subtree and calls {{LogicalPlan.refresh()}} on these nodes. However > {{LogicalPlan.refresh()}} is also refreshing its children, as a result > refreshing a large view can be quite expensive. -- This message was sent by Atlassian JIRA (v6.4.14#64029) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscr...@spark.apache.org For additional commands, e-mail: issues-h...@spark.apache.org
