mvn -f sd-market-data-switch-operation spring-boot:run
curl localhost:8080/v1/service-domain
# or deploy onto Kubernetes (Cilium eBPF mesh)
helm upgrade --install sd-market-data-switch-operation ./helm -n bian-reference-data
FAQQuestions
What is the BIAN “Operate” functional pattern?
An Operate service domain keeps a piece of operational or technical capability running day to day. Market Data Switch Operation applies it to the Market Data Feed.
What is a BIAN service domain?
BIAN (the Banking Industry Architecture Network) decomposes a bank into independent service domains, each owning exactly one business capability. Market Data Switch Operation is the service domain for Reference Data; it manages the Market Data Feed Operating Session and exposes it through standard BIAN action terms.
What business area does Market Data Switch Operation belong to?
Market Data Switch Operation sits in the Reference Data business area — the golden-source reference-data backbone that every other service domain reads from. It runs in the bian-reference-data namespace as one independent Spring Boot microservice.
Is Market Data Switch Operation production-ready?
It is an educational reference implementation: a real BIAN REST API over an in-memory store, ready to be filled with domain logic. It is not a live bank and is not affiliated with BIAN.
