The record

Product: FoundationDB is a distributed database that stores structured data across clusters of commodity servers as an ordered key-value store.
Transactions: All reads and writes use fully ACID transactions that can span multiple machines.
Data models: The core API is an ordered key-value store, while richer data models can be added through layers.
Scalability: FoundationDB scales out by adding machines and automatically handles data redundancy, partitioning, and caching.
Fault tolerance: Data is replicated across multiple servers, and the system automatically finds a new location for a lost copy when a server fails.
Workloads: FoundationDB is optimized for OLTP and can also support OLAP through ordered range reads.
Backups: Its integrated backup system creates scheduled moment-in-time snapshots of the distributed database on a remote file system.
Layers: Applications can use FoundationDB directly or through stateless layers that add data models, algorithms, or frameworks.
Language bindings: Officially supported client bindings are C, Go, Python, Java, and Ruby.
Security: FoundationDB supports TLS for communication security and authentication, but cluster connections are unencrypted by default.
Support: The project provides community forums for technical and user discussions.
Limit: query language: The FoundationDB core does not include a separate query language; query languages can be implemented in layers.
Limit: transaction duration: Read/write transactions lasting over five seconds cannot commit.
Platform caveat: The macOS server is intended for single-machine development, while Linux is described as the best-tested and most performant platform for multi-machine clusters.
