autocol vs lumpi vs nodedb-columnar
Side-by-side comparison of Rust crates
48
autocol
experimentalv0.1.2
Reversible, schema-free auto-columnar transform: reshape line-oriented data so a general compressor (zstd/brotli) sees per-column-homogeneous streams. A pre-pass, not a compressor. decode(encode(x)) == x.
43
lumpi
experimentalv9.0.5
Grep compressed JSONL/CSV log archives without decompressing. Columnar encoding reaches Zstd L19 ratio at L9 speed.
55
nodedb-columnar
experimentalv0.3.0
Columnar segment format and memtable for NodeDB analytical storage
