What is snappy?

Snappy is an open-source compression and decompression library developed by Google for fast and efficient data compression. Snappy is designed to be used in high-performance systems and is optimized for speed and energy efficiency.

Some features of Snappy include:

  • Compression ratio: Snappy is designed to achieve a high compression ratio while still maintaining fast compression and decompression speeds. It typically compresses data at a ratio of 20-30%.
  • Speed: Snappy is very fast, and can compress and decompress data at up to 250 MB per second on a single CPU core. It is designed to be used in real-time systems where speed is critical.
  • CPU usage: Snappy is designed to use as little CPU as possible, making it ideal for use in low-power devices and systems with limited resources.
  • Portability: Snappy is a cross-platform library and can run on a wide range of operating systems including Windows, Linux and macOS.
  • Compression quality: In general, Snappy prioritizes speed over compression quality. However, it still produces a good compression ratio compared to other fast compression algorithms.

Snappy is used in a wide range of applications, including databases, web servers, and messaging systems. It is also used by several large companies including Google, Facebook, and LinkedIn.
