> Add basic Variant Type support in Hive
> --------------------------------------
>
> Key: HIVE-29184
> URL: https://issues.apache.org/jira/browse/HIVE-29184
> Project: Hive
> Issue Type: Sub-task
> Reporter: Denys Kuzmenko
> Priority: Major
>
> Introduces the Variant data structure to represent semi-structured data and a
> new SQL type variant
> {code:java}
> class BinaryVariant implements Variant {
> private final byte[] value;
> private final byte[] metadata;
> // The variant value doesn't use the whole `value` binary, but starts
> from its `pos` index and
> // spans a size of `valueSize(value, pos)`. This design avoids frequent
> copies of the value
> // binary when reading a sub-variant in the array/object element.
> private final int pos;
> }
> {code}
