summary

Narayana is a Java transaction library used in WildFly and Quarkus and provides multiple modules: JTA with XA two‑phase commit for DBs, JTS/XTS bridging via WS- for distributed RPC, LRA implementing saga callbacks over HTTP for long‑running workflows, and a software transactional memory* implementation offering optimistic in‑memory concurrency. Code quickstarts on the linked GitHub show annotated examples, explicit enlist/registration calls, cross‑JVM context propagation and working commit/compensate callbacks so the features are demonstrated with runnable samples.
