Snappy
Snappy is a high-performance lossless compression library implemented in C++. It provides data reduction methods that perfectly restore original information, focusing on system-level efficiency and processing velocity across different platforms.
The library prioritizes high-speed data compression and decompression over achieving the maximum possible compression ratio. It is designed for real-time stream compression to reduce bandwidth usage without introducing significant processing latency.
The implementation covers high-velocity data shrinking and rapid restoration. It includes resilient data extraction capabilities that use input validation to prevent system crashes when encountering corrupted or malicious data.
