Description

Highly scalable database system, designed for managing session and subscriber data in modern mobile communication networks

CockroachDB 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.

An open source immutable (append-only) database with cryptographic verification which makes it tamper-resistant and fully auditable.

SpaceTime is a spatio-temporal DBMS with a focus on performance.
