Snappy is a library that uses very effective algorithms for compression and decompression of data. However, the goal is not to maximize compression or compatibility with other compression libraries but to focus on speed and reusable compression. HBase supports different compression mechanisms such as lzo, gzip, or snappy. Gzip comes built in with HBase while lzo/snappy compression needs to be configured separately. When creating a table, you can specify the compression/compression library; HFiles are compressed when written to disk if compression is used.

How to do it…

  1. Let's log in to our HBase setup.
