scottcarey opened a new pull request #303: AVRO-2162 Adds Zstandard compression
to the Avro File Format (Java)
URL: https://github.com/apache/avro/pull/303
Adds TestCodecs to cover all file compression Codecs.
Consolidates common code in Codecs into OutputStreamCodec
and OutputInputStreamCodec abstractions.
Fixes DataFileStream so that Codecs can return DirectByteBuffers
or Heap ByteBuffers with non-zero offset.

> Add Zstandard compression to avro file format
> ---------------------------------------------
>
> Key: AVRO-2162
> URL: https://issues.apache.org/jira/browse/AVRO-2162
> Project: Avro
> Issue Type: Improvement
> Components: java
> Reporter: Scott Carey
> Priority: Major
>
> I'd like to add Zstandard compression for Avro.
> At compression level 1 It is almost as fast as Snappy at compression, with
> compression ratios more like gzip. At higher levels of compression, it is
> more compact than gzip -9 with much lower CPU when compressing and roughly 3x
> faster decompression.
>
> Adding it to Java is fairly easy. We'll need to say something about it in
> the spec however, as an 'optinal' codec.
