Davies Liu resolved SPARK-10343. -------------------------------- Resolution: Fixed Assignee: Davies Liu Fix Version/s: 2.0.0 > Consider nullability of expression in codegen > --------------------------------------------- > > Key: SPARK-10343 > URL: https://issues.apache.org/jira/browse/SPARK-10343 > Project: Spark > Issue Type: Improvement > Components: SQL > Reporter: Davies Liu > Assignee: Davies Liu > Priority: Critical > Fix For: 2.0.0 > > > In codegen, we didn't consider nullability of expressions. Once considering > this, we can avoid lots of null check (reduce the size of generated code, > also improve performance). > Before that, we should double-check the correctness of nullablity of all > expressions and schema, or we will hit NPE or wrong results. -- 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
