CoinWorld News: Sui Launches Tidehunter Database. The core design of Tidehunter focuses on building a write path that fully leverages modern SSD performance while avoiding contention. All write operations pass through a ultra-fast lock-free write-ahead log (WAL), capable of handling millions of operations per second. Tidehunter uses writable memory-mapped files instead of system calls for each write. Persistence is managed asynchronously by a background service thread responsible for file growth management and periodic synchronization. Additionally, Tidehunter employs a dedicated uniform lookup index aimed at reducing read latency on the critical path.
