ExtiR

ExtiR, short for Extensible Real-time Information Router, is a cross-platform software framework designed to route, transform, and deliver real-time data across distributed systems. The project emphasizes modularity, low latency, and extensibility, enabling organizations to integrate heterogeneous data sources and destinations through a consistent, policy-driven pipeline.

At its core, ExtiR provides a routing engine, a collection of adapters (for input and output), and a processor pipeline where data can be filtered, enriched, or transformed. A modular policy engine governs routing decisions based on metadata, content, and trust requirements, allowing dynamic reconfiguration without downtime. The architecture supports pluggable serializers, timestamping, and backpressure control to maintain stability under varying load.

ExtiR supports multiple transport and serialization options, including JSON, XML, and binary formats such as Protocol Buffers. It can ingests from message queues, streaming platforms, or direct sockets, and publishes to databases, data lakes, or other services. Security features include TLS, mutual TLS, and pluggable authentication and authorization mechanisms, while observability is provided through metrics, distributed tracing, and centralized logging.

Originating as an open-source community project in the early 2020s, ExtiR is maintained by a diverse group of contributors and governed by an informal code of conduct and contribution guidelines. Releases follow a semantic versioning scheme, and the project maintains a public issue tracker and documentation hub.

Typical use cases include real-time analytics, IoT data routing, microservices integration, and data synchronization across hybrid cloud environments. By decoupling producers and consumers and providing policy-based routing, ExtiR aims to reduce coupling and latency while improving observability.
