Summary: 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
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.
