**[Sui Launches Tidehunter Database]** According to Golden Finance, Sui has launched the 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 flow through an ultra-high-speed, lock-free Write-Ahead Log (WAL), capable of handling millions of operations per second. Tidehunter replaces system calls for each write with writable memory-mapped files. Persistence is handled asynchronously by background service threads, which manage file growth and periodic synchronization. Additionally, Tidehunter utilizes a dedicated uniform lookup index designed to reduce read latency on critical paths.
