> Quoting from BigTable paper: "Many clients use a two-pass custom compression
> scheme. The first pass uses Bentley and McIlroy's scheme, which compresses
> long common strings across a large window. The second pass uses a fast
> compression algorithm that looks for repetitions in a small 16 KB window of
> the data. Both compression passes are very fast—they encode at 100-200 MB/s,
> and decode at 400-1000 MB/s on modern machines."
> The goal of this patch is to integrate a similar compression scheme in HBase.
