> PARQUET-970 added these codecs to the format. We have LZ4 in the toolchain already and I just added zstd: [https://gerrit.cloudera.org/#/c/13079/]
> These codec probably offer a better trade-off of density and speed than snappy or gzip.
> [https://github.com/apache/arrow/pull/807/files] might be a useful crib sheet for how to add a compressor.
> LZ4 support will be added using: https://issues.apache.org/jira/browse/IMPALA-8617
