title: How does one achieve parallel gzip compression with Python?
body: <p><a href="https://stackoverflow.com/questions/9518705/big-file-compression-with-python">Big file compression with python</a> gives a very nice example on how to use e.g. bz2 to compress a very large set of files (or a big file) purely in Python.</p>
  
  <p><a href="http://www.zlib.net/pigz" rel="noreferrer">pigz</a> says you can do better by exploiting parallel compression.
  To my knowledge (and Google search) insofar I cannot find a Python equivalent to do so in pure Python code.</p>
  
  <p>Is there a parallel Python implementation for <code>pigz</code> or equivalent?</p>
