TigerBeetle
An open-source financial transactions database built on debit/credit, published under the Apache License 2.0.
TigerBeetle is a database for online transaction processing, designed around accounts and transfers rather than tables. Every transfer debits one account and credits another under strict serializability. Transfers can run in two phases: a pending transfer reserves funds and is then posted, voided or left to expire, and a partial post moves part of the amount and returns the rest. That model fits card authorizations and other holds.
The software is production-ready on Linux, with client libraries for Python, Java, Node.js, .NET, Go and Ruby. TigerBeetle says one query can carry up to 8,189 transactions and that a cluster scales up on six replicated machines rather than partitioning. The code is open source under Apache 2.0 with no contributor license agreements. Applications define their own account structure on top.
