Chao Sun reassigned SPARK-36612: -------------------------------- Assignee: Szehon Ho > Support left outer join build left or right outer join build right in > shuffled hash join > ---------------------------------------------------------------------------------------- > > Key: SPARK-36612 > URL: https://issues.apache.org/jira/browse/SPARK-36612 > Project: Spark > Issue Type: Sub-task > Components: SQL > Affects Versions: 3.2.0 > Reporter: mcdull_zhang > Assignee: Szehon Ho > Priority: Major > > Currently spark sql does not support build left side when left outer join (or > build right side when right outer join). > However, in our production environment, there are a large number of scenarios > where small tables are left join large tables, and many times, large tables > have data skew (currently AQE can't handle this kind of skew). > Inspired by SPARK-32399, we can use similar ideas to realize left outer join > build left. > I think this treatment is very meaningful, but I don’t know how members > consider this matter? -- 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
