How does LZ77 work?
LZ77 iterates sequentially through the input string and stores any new match into a search buffer.
The process of compression can be divided in 3 steps: Find the longest match of a string that starts at the current position with a pattern available in the search buffer..
How is data compressed in zip?
How do ZIP files work? ZIP files encode information into fewer bits by removing redundant data.
This “lossless data compression” ensures all the original data is intact..
Is LZ4 better than ZSTD?
If you need a fast and efficient compression algorithm, LZ4 is a good option.
If you need a balance between compression ratio and speed, ZSTD is a good choice..
Why use LZ4?
With LZ4, compression can either be done in a stream or in blocks.
Higher compression ratios can be achieved by focusing on finding best matches, which then results in both a smaller output and faster decompression..
LZ4 is lossless compression algorithm, providing compression speed at 400 MB/s per core, scalable with multi-cores CPU.
It features an extremely fast decoder, with speed in multiple GB/s per core, typically reaching RAM speed limits on multi-core systems.
