ZSTD Compression (Zstandard)
ZSTD combines LZ77-style dictionary matching (find repeated byte sequences, replace with back-references) with two entropy coders: Finite State Entropy (FSE) for match lengths and offsets, and Huffman coding for literal bytes. This three-stage pipeline achieves gzip-level compression ratios at LZ4-level speeds
