LZ4
LZ4 is a lossless compression algorithm that focuses on compression and decompression speed. It allows fast data compression and real-time decompression. LZ4 is open-source and cross-platform compatible.
LZ4: Fast Lossless Compressions
A high-performance lossless compression algorithm for fast data compression and real-time decompression, with open-source and cross-platform compatibility
What is LZ4?
LZ4 is an extremely fast lossless compression algorithm created by Yann Collet. It prioritizes compression and decompression speed over the compression ratio, making it well-suited for applications that require fast data access and real-time compression/decompression.
Some key features of LZ4 include:
- Extremely fast compression and decompression speeds, faster than other algorithms like DEFLATE or Brotli
- Reasonably good compression ratios, although not as high as Zstandard or Brotli
- Very memory efficient during compression and decompression
- Highly portable and cross-platform compatible - works on everything from embedded devices to high-end servers
- Open-source and royalty-free, published under BSD license
LZ4 is commonly used for applications like databases and analytics that need to perform compression but require very fast access to data. It strikes a good balance between compression speed and ratio for these use cases. Key advantages over Brotli and Zstandard are its decompression speed and low memory requirements.
Overall, LZ4 is an excellent choice when you need lightweight real-time compression and fast decompression speeds for your application data.
