Currently the only encoding method supported by Alteryx Avro format is deflate. Please consider improving this to include google snappy approach.
This codec method is referenced in the Avro documentation for supported codex.

Really, Alteryx! You do not support snappy yet?
Please, having snappy would be really useful for avro processing.
