Github user sekruse commented on the pull request: https://github.com/apache/flink/pull/762#issuecomment-109385326 Okay, I did not further explain the internals but only how to employ the deflate and GZip support. I think, to make compression extensible or customizable (which would be worthwhile in my opinion), we should make small changes to the code wrt. to its usability. That however does not match the contents of the associated JIRA.
