Perfect, thanks! Testing out the Snappy compressor now and will push it back if it works as
planned. Cheers.

Take a look at the testCompression() method in AbstractFileOutputOperatorTest.java for an

What is the recommended way to write compressed data to HDFS? Should I extend AbstractFileOutputOperator
or is there existing support for this via a config?

What formats are presently supported and if extending Apex to support Snappy or Lz4 what would
that look like?

Thanks in advance!
