Inside TigerBeetle: zero-allocation design that kills tail latency
A deep-dive deconstructs why TigerBeetle, the Zig-written financial ledger, treats the OS kernel and memory fragmentation as the real bottleneck — not the query planner. It statically pre-allocates every byte at startup, locks the allocator, and runs a single-threaded loop with direct I/O and Viewstamped Replication. The payoff: hundreds of thousands of transactions per second with predictable sub-millisecond tails. Worth a read for anyone building high-throughput systems.
