Parallel Universe

Parallel Universe provides a stack and JVM-based libraries to build concurrent, scalable, and fault-tolerant applications. It emphasizes using lightweight threads, actors, and in-memory data structures to scale with modern multi-core hardware while keeping existing programming languages and styles intact.

The stack comprises Comsat (fiber-aware Java web APIs with Java servlets, JAX-RS, HTTP clients and JDBC), Quasar (an open source JVM library that adds lightweight fibers, Go-like channels, and Erlang-like actors with supervision), SpaceBase (an in-memory spatial/geo-spatial database for real-time updates), and Galaxy (a distributed in-memory data grid that horizontally scales Quasar’s actors across a cluster with cache-coherence and minimal IO for queries/transactions). Together, these components enable writing asynchronous, highly concurrent software with familiar sequential code, supporting hundreds of thousands to millions of lightweight threads on a single JVM and scalable, low-latency data operations across a cluster.

Who it’s for: Developers and engineering teams building scalable, concurrent applications who want to leverage lightweight threading and in-memory data capabilities without rewriting existing code.
