On the strange design of TigerBeetle Database

1. Static allocation

In TigerBettle, all memory is allocated up front at startup. No heap allocation occurs during steady-state operation.

TigerBeetle uses Zig’s comptime to calculate struct sizes, precompute memory layouts and validate alignment and bounds. This guarantees memory fits exactly and no surprises at runtime

2. The database exclusive for niche markets

TigerBeetle is special because it is not a general-purpose database — it is a purpose-built financial ledger database that optimizes for absolute correctness, determinism, and performance under extreme load.
