launching kiban a storage engine i wrote from scratch in rust. it read 100M records in 57s. RocksDB took 7 min cached point read: 1.09 µs. 2.6x RocksDB, 1.3x LMDB 16 writers, every write synced: 14,101/s. RocksDB 12,830 it wasn't always like this. kiban once returned 8 when the answer was 40. sync() was reporting success on data a power cut would've wiped, and snapshots were losing data. my bugs. they're all written up on the site so i tested it harder. simulated power loss, millions of crash seeds, kill -9 and reopen 1000 times files never change after they're written so each one gets a perfect hash. you compute where the key is instead of searching for it. LMDB can't do that, its pages change in place RocksDB still beats it on long write runs by about 3x, and on memory and disk. linux only, no transactions, not production ready. warm cache, my laptop every benchmark has a receipt and a button that copies a prompt so your llm can explain it. tell me if it finds something kiban-website.vercel.app p.s. see the site on laptop, i didn't optimize it for the phone, it'd be a major disservice
