Jonathan Gray created SPARK-15258: ------------------------------------- Summary: Nested/Chained case statements generate codegen over 64k exception Key: SPARK-15258 URL: https://issues.apache.org/jira/browse/SPARK-15258 Project: Spark Issue Type: Bug Components: SQL Affects Versions: 1.6.1 Reporter: Jonathan Gray
Nested/Chained case-when expressions generate a codegen goes beyound 64k exception. A test attached demonstrates this behaviour. I'd like to try and fix this but don't really know the best place to start. Ideally, I'd like to avoid the codegen fallback as with large volumes this hurts performance. This is similar(ish) to SPARK-13242 but I'd like to see if there are any alternatives to the codegen fallback approach. -- This message was sent by Atlassian JIRA (v6.3.4#6332) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscr...@spark.apache.org For additional commands, e-mail: issues-h...@spark.apache.org
