Multi-Protocol Database Platform

Orbit-RS is a distributed database that speaks several wire protocols over one durable, replicated store. Its goal is full compatibility with PostgreSQL 18, measured against the PostgreSQL 18 conformance corpus; each other protocol layer targets the latest version of the system it imitates (see the protocol table in Project Overview). Compatibility, maturity and performance are stated only as measured: a conformance pass rate with its date, a maturity label with its evidence, and benchmark results with their method.

What is Orbit-RS?

Orbit-RS is a multi-protocol database platform that combines the power of virtual actor architecture with comprehensive database capabilities. It’s designed as a next-generation system that unifies:

Performance

Not yet benchmarked. Earlier throughput, latency, binary-size and JVM-comparison figures were removed because no benchmark backed them (ADR 0016).
