  1. Snappy is a compression/decompression library. It does not aim for
  2. maximum compression, or compatibility with any other compression
  3. library; instead, it aims for very high speeds and reasonable
  4. compression. For instance, compared to the fastest mode of zlib,
  5. Snappy is an order of magnitude faster for most inputs, but the
  6. resulting compressed files are anywhere from 20% to 100% bigger. (For
  7. more information, see "Performance", below.)
  8. Snappy has the following properties:
  9. * Fast: Compression speeds at 250 MB/sec and beyond, with no assembler
  10. code. See "Performance" below.
  11. * Stable: Over the last few years, Snappy has compressed and
  12. decompressed petabytes of data in Google's production environment. The
  13. Snappy bitstream format is stable and will not change between
  14. versions.
  15. * Robust: The Snappy decompressor is designed not to crash in the face
  16. of corrupted or malicious input.
  17. * Free and open source software: Snappy is licensed under a BSD-type
  18. license. For more information, see the included COPYING file.
  19. Snappy has previously been called "Zippy" in some Google presentations
  20. and the like.
