FoundationDB is an open-source multimodel database, acquired by Apple in 2015 and then open sourced in April 2018. The core of FoundationDB is a distributed key-value store, which provides strict serializability transactions. One of the interesting aspects of FoundationDB is its concept of layers to offer additional models. These layers are essentially stateless components built on top of the core key-value store, such as the Record layer and the Document layer. FoundationDB sets a high standard with its Simulation testing where they run daily tests simulating various system failures. With its performance, rigorous testing and easy operability, FoundationDB is not just a database but can also be used by those looking to build distributed systems where they can use FoundationDB as a core primitive on which to build their system.
