> Project: Hive
> Issue Type: Improvement
> Reporter: Panagiotis Garefalakis
> Assignee: Panagiotis Garefalakis

> There is no native support currently meaning that these types end up being
> serialized as multi-key columns which is much slower (iterating through batch
> columns instead of writing a value directly)
