confirmbs

Confirmbs is a software protocol and library designed to provide deterministic confirmation of event processing in distributed systems. It offers a lightweight mechanism for collecting acknowledgments from participating services and for committing a business state only after a defined threshold of confirmations is reached. The approach aims to improve reliability, traceability, and consistency in asynchronous architectures without requiring full two‑phase commit.

Origin and terminology

The term confirmbs is used in some practitioner communities to describe a confirmation-based state discipline. In this context, “BS” is commonly interpreted as “business state” or “backing state,” signaling that a given state change is only finalized when a specified set of services has affirmed the change. The concept originated in open‑source discussions around event-driven microservices and has since been implemented in several lightweight libraries and integrations.

Architecture and components

Confirmbs typically comprises a client library, a coordinating component (or broker), and optional adapters for common message buses. The core data model centers on a ConfirmEvent, which includes an event id, origin, payload, a required_confirmations count, and a status field. A coordinator aggregates confirmations from participating services and triggers a final commit or compensating action once the required number of confirmations is reached or a timeout occurs. The system emphasizes idempotent processing, traceable provenance, and pluggable backoff and retry policies.

Usage and workflow

A typical workflow begins with a producer publishing an event to the system. Downstream services process the event and emit confirmations back to the coordinator. When the configured confirmation threshold is met, the system marks the business state as committed and may publish a finalization event. If confirmations fail to arrive within a deadline, compensating actions or rollbacks may be initiated. The model supports partial failures and aims to minimize the impact of delayed components.

Reception and considerations

Confirmbs can increase reliability and observability in distributed workflows, but it adds architectural complexity and potential latency. It is best suited for scenarios where finality of a state is more important than ultra-fast processing, such as business transactions requiring auditability and clear rollback paths.
