Kazuaki Ishizaki created SPARK-20253: ----------------------------------------
Summary: Remove unnecessary nullchecks of a return value from Spark runtime routines in generated Java code Key: SPARK-20253 URL: https://issues.apache.org/jira/browse/SPARK-20253 Project: Spark Issue Type: Improvement Components: SQL Affects Versions: 2.2.0 Reporter: Kazuaki Ishizaki While we know several Spark runtime routines never return null (e.g. {{UnsafeArrayData.toDoubleArray()}}, the generated code by Catalyst always checks whether the return value is null or not. It is good to remove this nullcheck for reducing Java bytecode size and reducing the native code size. -- This message was sent by Atlassian JIRA (v6.3.15#6346) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscr...@spark.apache.org For additional commands, e-mail: issues-h...@spark.apache.org
