Liang-Chi Hsieh created SPARK-21717: ---------------------------------------
Summary: Decouple the generated codes of consuming rows in operators under whole-stage codegen Key: SPARK-21717 URL: https://issues.apache.org/jira/browse/SPARK-21717 Project: Spark Issue Type: Improvement Components: SQL Affects Versions: 2.2.0 Reporter: Liang-Chi Hsieh It has been observed in SPARK-21603 that whole-stage codegen suffers performance degradtion, if generated functions are too long to be optimized by JIT. We basically produce a single function to incorporate generated codes from all physical operators in whole-stage. Thus, it is possibly to grow the size of generated function over a threshold that we can't have JIT optimization for it anymore. This ticket is trying to decouple the logic of consuming rows in physical operators to avoid a giant function processing rows. -- This message was sent by Atlassian JIRA (v6.4.14#64029) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscr...@spark.apache.org For additional commands, e-mail: issues-h...@spark.apache.org
