title: Transparent SQLite Data Compression
body: <p>I am looking for an existing solution for transparent SQLite 3 zlib compression using <a href="http://www.sqlite.org/c3ref/vfs.html" rel="noreferrer">a custom VFS implementation</a> and <a href="http://www.sqlite.org/c3ref/io_methods.html" rel="noreferrer">a custom IO methods implementation</a>.</p>
  
  <p>Is anyone aware of an existing project that already does that, or will I have to roll my own? I vaguely remember seeing something similar a year ago, but can't find it anymore.</p>
