Apache Spark reassigned SPARK-22383: ------------------------------------ Assignee: Apache Spark > Generate code to directly get value of primitive type array from ColumnVector > for table cache > --------------------------------------------------------------------------------------------- > > Key: SPARK-22383 > URL: https://issues.apache.org/jira/browse/SPARK-22383 > Project: Spark > Issue Type: Bug > Components: SQL > Affects Versions: 2.2.0 > Reporter: Kazuaki Ishizaki > Assignee: Apache Spark > > This JIRA generates the Java code to directly get a value for a primitive > type array in ColumnVector without using an iterator for table cache (e.g. > dataframe.cache). This JIRA improves runtime performance by eliminating data > copy from column-oriented storage to {{InternalRow}} in a > {{SpecificColumnarIterator}} iterator for primitive type. -- 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
