Snappy is a free program library for compressing and decompressing data. The algorithm was developed by Google and published in 2011 under a free BSD license . It is designed for high compression and decompression speeds, so the compression rate is significantly worse than that of zlib . Snappy is faster than the comparable LZO algorithm .
Snappy is used by Google's own programs MapReduce and Bigtable as well as the Apache projects Hadoop and Lucene .
technology
Snappy only outputs whole bytes. No entropy coding is used.
