Apache Spark reassigned SPARK-26548: ------------------------------------ Assignee: (was: Apache Spark) > Don't block during query optimization > ------------------------------------- > > Key: SPARK-26548 > URL: https://issues.apache.org/jira/browse/SPARK-26548 > Project: Spark > Issue Type: Improvement > Components: SQL > Affects Versions: 2.4.0 > Reporter: Dave DeCaprio > Priority: Minor > Labels: sql > > In Spark 2.4.0 the CacheManager was updated so it will not execute jobs while > it holds a lock.This was introduced in -SPARK-23880.- > The CacheManager still holds a write lock during the execution of the query > optimizer. For complex queries the optimizer can run for a long time (we see > 10-15 minutes for some exceptionally large queries). This allows only 1 > thread to optimize at once. -- This message was sent by Atlassian JIRA (v7.6.3#76005) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscr...@spark.apache.org For additional commands, e-mail: issues-h...@spark.apache.org
