A real world use case with OSGi R7
summary
Rebuild of a radio search backend into OSGi R7 microservices uses JAX-RS Whiteboard, PushStreams, the Configurator, Remote Service Admin and BND/Felix; data model via EMF, Lucene index, MongoDB as source, MQTT for remote transport. Indexing 55,000 stations drops from ~30 minutes to 4–5 minutes and peak memory from ~24 GB to ~4 GB by using pushback streaming and batching; bundles deploy remotely into a Docker Felix for live debugging, and the gecko open‑source framework implements the production setup.
