Denys Kuzmenko updated HIVE-29184:
----------------------------------
Description:
Introduces the Variant data structure to represent semi-structured data and a
new SQL type variant, with initial Hive support for reading and writing Variant
data in Iceberg tables.
{code:java}
class Variant {
private final byte[] value;
private final byte[] metadata;
}
{code}
Hive Deserializer converts Iceberg Variants into Hive Variants during access.

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}
