> In our testing, compressing partitions while writing them to checkpoints on
> HDFS using snappy helped performance significantly while also reducing the
> variability of the checkpointing operation. In our tests, checkpointing time
> was reduced by 3X, and variability was reduced by 2X for data sets of
> compressed size approximately 1 GB.
