Aliaksei Sandryhaila updated ORC-45:
------------------------------------
Issue Type: Wish (was: Bug)
> Support ZSTD Dictionary Compression
> ------------------------------------
>
> Key: ORC-45
> URL: https://issues.apache.org/jira/browse/ORC-45
> Project: Orc
> Issue Type: Wish
> Reporter: Charles Pritchard
>
> ZSTD provides superior processing performance in comparison to deflate/gzip.
> Dictionary compression provides yet another opportunity for improvement, when
> applied to columns.
> Implementing dictionary compression per-column may enable other code to be
> written, such as per-column encryption, which while mentioned in ORC-14,
> would be taking a different form.
