DescriptionCockroachDB is a distributed database architected for modern cloud applications. It is wire compatible with PostgreSQL and backed by a Key-Value Store, which is either RocksDB or a purpose-built derivative, called Pebble.A native JSON - document store inspired by Lotus Notes, scalable from globally distributed server-clusters down to mobile phones.An open source immutable (append-only) database with cryptographic verification which makes it tamper-resistant and fully auditable.A robust multi-value DBMS comprising development tools and middlewareA .NET Object Database that can be embedded/distributed and extended to a graph data model (VelocityGraph)
