The article examines how SQLite can achieve impressive transaction throughput despite its limitations, such as single-writer architecture. It contrasts SQLite's performance with traditional network databases, demonstrating that eliminating network latency allows for significantly higher transactions per second. The author also discusses batching and the use of SAVEPOINTs for transaction management.

Maintaining consistency in a system comprised of separate databases can be challenging, particularly in the absence of transactions. The article discusses the importance of defining a system of record versus a system of reference and emphasizes the Write Last, Read First principle to ensure safety properties like consistency and traceability in financial transactions.

TigerBeetle is presented as a groundbreaking database designed for modern transactional needs, prioritizing debits and credits as core primitives, and built with a unique architecture that emphasizes distributed systems and fault tolerance. The article explores its innovative features, including deterministic simulation testing and the use of the Zig programming language, positioning TigerBeetle as a leader in the evolution of database technology for real-time transactions.
