TigerBeetle

TigerBeetle is an open-source financial transactions database designed to power high-volume online transaction processing (OLTP). Its purpose-built system combines a global consensus protocol with a local storage engine to prioritize performance, consistency, availability, and durability. The company says TigerBeetle can deliver high throughput and predictable low latency, including under heavy transaction contention, while storing billions of transactions in a cluster.

At the core of the product is debit-and-credit processing, supported by a universal schema and strict serializability intended to help maintain transaction integrity. TigerBeetle is designed for workloads such as payments and other systems that need reliable, fast transaction handling. Its tiered storage engine uses CPU caches, memory, and NVMe storage, and its architecture emphasizes efficient use of hardware.

TigerBeetle is available as Apache 2.0 open-source software, with installation options for Linux, macOS, and Windows. The site describes it as production-ready on Linux and lists integrations with Python, Java, Node.js, .NET, Go, and Ruby. TigerBeetle also offers a cloud option, alongside documentation, pricing information, and technical articles.
