Michael Armbrust updated SPARK-3294: ------------------------------------ Assignee: Cheng Lian > Avoid boxing/unboxing when handling in-memory columnar storage > -------------------------------------------------------------- > > Key: SPARK-3294 > URL: https://issues.apache.org/jira/browse/SPARK-3294 > Project: Spark > Issue Type: Improvement > Components: SQL > Affects Versions: 1.0.2, 1.1.0 > Reporter: Cheng Lian > Assignee: Cheng Lian > Priority: Critical > > When Spark SQL in-memory columnar storage was implemented, we tried to avoid > boxing/unboxing costs as much as possible, but {{javap}} shows that there > still exist code that involves boxing/unboxing on critical paths due to type > erasure, especially methods of sub-classes of {{ColumnType}}. Should > eliminate them whenever possible for better performance. -- This message was sent by Atlassian JIRA (v6.2#6252) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscr...@spark.apache.org For additional commands, e-mail: issues-h...@spark.apache.org
