------------------------------------
Summary: Support ZSTD Dictionary Compression
Key: ORC-45
URL: https://issues.apache.org/jira/browse/ORC-45
Project: Orc
Issue Type: Bug
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.
