FoundationDB, a database company, was purchased by Apple back in 2015. As described in today's announcement, FoundationDB is a distributed datastore that's been designed from the ground up to be deployed on clusters of commodity hardware.
By open sourcing the project to drive development, FoundationDB is aiming to become "the foundation of the next generation of distributed databases.
The vision of FoundationDB is to start with a simple, powerful core and extend it through the addition of "layers". The key-value store, which is open sourced today, is the core, focused on incorporating only features that aren't possible to write in layers. Layers extend that core by adding features to model specific types of data and handle their access patterns.Following the open sourcing of FoundationDB, the company believes the quantity and variety of FoundationDB layers will develop rapidly. FoundationDB has adopted a new set of project governance rules and a code of conduct for community development.
The fundamental architecture of FoundationDB, including its use of layers, promotes the best practices of scalable and manageable systems. By running multiple layers on a single cluster (for example a document store layer and a graph layer), you can match your specific applications to the best data model. Running less infrastructure reduces your organization's operational and technical overhead.
The source for FoundationDB is available on Github as of today, and those who wish to join the project are encouraged to visit the FoundationDB community forums, submit bugs, and make contributions to the core software and documentation.
