Apache Spark reassigned SPARK-40377: ------------------------------------ Assignee: Apache Spark > Allow customize maxBroadcastTableBytes and maxBroadcastRows > ----------------------------------------------------------- > > Key: SPARK-40377 > URL: https://issues.apache.org/jira/browse/SPARK-40377 > Project: Spark > Issue Type: Improvement > Components: SQL > Affects Versions: 3.4.0 > Reporter: LeeeeLiu > Assignee: Apache Spark > Priority: Major > Attachments: 截屏2022-09-07 20.40.06.png, 截屏2022-09-07 20.40.16.png > > > Recently, we encountered some driver OOM problems. Some tables with large > data volume were compressed using Snappy and then broadcast join was > performed, but the actual data volume was too large, which resulted in driver > OOM. > The values of maxBroadcastTableBytes and maxBroadcastRows are hardcoded, 8GB > and 512000000 respectively. Maybe we can allow customization of these values, > configure smaller values according to different scenarios, and prohibit > broadcast joins for tables with large data volumes to avoid driver OOM. -- 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
