Sampled — shipped under file-level sampling, not individually fact-checkedcommunity attestations: 0✓ / 0✗
Steps
Deploy Open Match's core gRPC services (Frontend, Backend, Query) into a Kubernetes cluster via the official install manifests/Helm chart
Write a Director that periodically calls the Backend service's FetchMatches, passing your MatchFunction's match profiles
Implement a custom MatchFunction (as a gRPC service) that reads pending tickets from the Query service and groups them into proposed matches using your own logic
Have game clients create tickets against the Frontend service and poll for assignment
Wire the Director to allocate a game server (e.g., via Agones) once a match is approved, then assign connection info back to tickets
Known gotchas
Open Match intentionally ships no matching algorithm -- you must implement the MatchFunction yourself; there's no default skill-based matcher
Scaling relies on Kubernetes autoscaling; under-provisioned Query/Backend pods become the bottleneck under high ticket volume
