Three Durability Modes, One WAL: Configurable Guarantees for Different Workloads

💡Typhon is an embedded, persistent, ACID database engine written in .NET that speaks the native language of game servers and real-time simulations: entities, components, and systems. It delivers full transactional safety with MVCC snapshot isolation at sub-microsecond latency, powered by cache-line-aware storage, zero-copy access, and configurable durability. Series: A Database That Thinks Like a Game Engine Why I’m Building a Database Engine in C# What Game Engines Know About Data That Databases Forgot Microsecond Latency in a Managed Language Deadlock-Free by Construction Three Durability Modes, One WAL (this post) MVCC at Microsecond Scale (coming soon) GitHub repo • :mailbox_with_mail: Subscribe via RSS Most databases pick one durability strategy at boot time. Typhon picks one per commit — and the surprising part isn’t the user-facing API, it’s that all three modes share the same WAL (Write-Ahead Log — every commit appends a record here before being durable) writer thread, the…
