Add compressor support for 'snappy', google's compressor
--------------------------------------------------------
Key: HBASE-3691
URL: https://issues.apache.org/jira/browse/HBASE-3691
Project: HBase
Issue Type: Task
Reporter: stack
Priority: Critical
Fix For: 0.92.0
http://code.google.com/p/snappy/ is apache licensed.
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.
