Deep dives
Breakthrough in Database Design
Euron Dirk Grief recognized a significant limitation in general-purpose databases for transaction processing, specifically their inefficiency in handling high transaction volumes. This realization led to the creation of Tiger Beetle, a specialized distributed database designed for financial transactions that offers dramatically faster performance—up to three orders of magnitude compared to traditional systems. The critical insight was centered on row locks in SQL transactions, which pose significant bottlenecks during data retrieval and processing. By focusing on optimizing transaction methods and redesigning the database's architecture, Tiger Beetle was born as a solution geared toward scaling financial operations without the constraints typical of legacy databases.
