You are right, that was poor wording. If we compare apples to apples: Traditional: must decompress entire file (even when streaming) - zstd -dc huge_logs.zst

You are right, that was poor wording. If we compare apples to apples: Traditional: must decompress entire file (even when streaming) - zstd -dc huge_logs.zst | grep "error" # 709 MB decompressed through memory Crystal: indexed search, skip to matches - cuz search huge_logs.cuz "error" # Only decompress matching blocks Thanks for pointing this up. We will update the readme file.
