Nicholas Telford updated HBASE-3691:
------------------------------------
Release Note: Added support for Google's Snappy compression codec.
Status: Patch Available (was: Open)
As far as I can tell this is all that's required in Hbase to add support for
Snappy. Since it's an optional runtime dependency, and we can guarantee the
class name (SnappyCodec) and it's interface (CompressionCodec) we're not
actually blocked by the addition of the CompressionCodec itself (HADOOP-7206).
I've tested this against the preliminary support for Snappy in HADOOP-7206, as
far as I can tell they're simply waiting on some licensing constraints to be
resolved (which doesn't affect this patch).

> bq. Snappy is a compression/decompression library. It does not aim for
> maximum compression, or compatibility with any other compression library;
> instead, it aims for very high speeds and reasonable compression. For
> instance, compared to the fastest mode of zlib, Snappy is an order of
> magnitude faster for most inputs, but the resulting compressed files are
> anywhere from 20% to 100% bigger. On a single core of a Core i7 processor in
> 64-bit mode, Snappy compresses at about 250 MB/sec or more and decompresses
> at about 500 MB/sec or more.
> bq. Snappy is widely used inside Google, in everything from BigTable and
> MapReduce to our internal RPC systems. (Snappy has previously been referred
> to as "Zippy" in some presentations and the likes.)
> Lets get it in.
