## What it is
Snappy is a fast compression/decompression library from Google that prioritizes very high throughput over maximum compression ratios. It offers a stable bitstream format, a robust decompressor that resists corrupted input, and speeds of roughly 250 MB/s compression and 500 MB/s decompression.

## Use cases
- compress data fast without high CPU cost
- speed up database or log file storage with lightweight compression
- compress network payloads where latency matters more than size
- decompress untrusted input safely without crashing
- replace zlib when compression speed is the bottleneck

## When to choose
- you need maximum compression/decompression speed and can accept larger output files
- you need a stable, battle-tested format used in production at petabyte scale
- you are compressing text, HTML, or structured data on 64-bit x86 hardware

## When to avoid
- you need the smallest possible compressed size rather than the fastest speed
- you need compatibility with gzip or other standard compression formats
- you target big-endian or non-64-bit platforms where performance degrades
- you are compressing already-compressed data like JPEG or PNG
