Kazuaki Ishizaki updated SPARK-20783:
-------------------------------------
Description:
Current {{ColumnVector}} handles uncompressed data for parquet.
For handling table cache, this JIRA entry adds {{OnHeapCachedBatch}} class to
have compressed data.
As first step of this implementation, this JIRA supports primitive data and
string types.
was:
Current {{ColumnVector}} accepts only primitive-type Java array as an input for
array. It is good to keep data from Parquet.
On the other hand, in Spark internal, {{UnsafeArrayData}} is frequently used to
represent array, map, and struct. To keep these data, this JIRA entry enhances
{{ColumnVector}} to keep UnsafeArrayData.
