This tracks integrating it into Hadoop. > {quote} > 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. > {quote} -- This message is automatically generated by JIRA.
