Cookbook Deploy Static Compute

Deployment Cookbook: Static MDS with Compute

Static MDS plus a compute tier - a projector that derives computed and interpolated content from what the other projectors serve, rather than sourcing an external feed. Add it when you want the platform to produce derived content: computed columns, curve interpolation, and functions from its computation libraries.

Audience: Architect, Operator. Start from Static MDS; this page adds one image.

The compute tier is the projector tier used as a compute node, described in Architecture: Advanced.

---

The same images, three ways to run them

This is the Static MDS deployment with one image added, mf-projector-compute. Everything from Static MDS applies unchanged, including how its MDS projectors find their ETA server; below is the delta.

Method	You launch it with	Ideal for
Conventional	the host ./run launcher	the standard install - this is the primary path
Docker	docker compose up	a demo or lab on a single machine
Kubernetes	standard Deployment / Service manifests	a cluster-managed fixed install

---

The image you add

Image	Role	Release
mf-projector-compute	Derives computed and interpolated content from other projectors' output	deploy-mf-projector-compute

It joins the Static MDS images: gateway, admin, core services, and one or more MDS projectors.

The compute projector hosts computation libraries. intrinsic (the SQL arithmetic and comparison operators) is always present; basic, math, and interpolation are available, with more to come. See the Image Catalog for what each library provides.

---

Conventional Static MDS with Compute

Install exactly as Static MDS, then add one more package:

1. Download and unpack the mf-projector-compute release above.
2. Edit its deployment-config/ for your environment. Point it at the pub/sub service so it can source the content it computes from - METAFLUENT_PUBSUB_ADAPTER_CONNECTION=mf-session:8900, or the equivalent in deployment-config/.
3. Set JAVA_HOME and start it with ./run.

Run more than one compute projector the same way when you want more computation throughput or resilience.

---

Docker Static MDS with Compute

Take the Static MDS Compose file and add this service:

  mf-projector-compute:
    image: ghcr.io/metafluent/mf-projector-compute-cfg-stable:milestone
    container_name: mf-projector-compute
    network_mode: host
    environment:
      METAFLUENT_HOST_UID: "${METAFLUENT_HOST_UID}"
      METAFLUENT_PUBSUB_ADAPTER_CONNECTION: "mf-session:8900"   # where it sources content to compute from
    volumes:
      - ./logs:/app/logs
      - ./data:/app/data

Bring it up with the rest: METAFLUENT_HOST_UID=$(id -u) docker compose up -d.

---

Kubernetes Static MDS with Compute

An example. Add this to the Static MDS manifests:

apiVersion: apps/v1
kind: Deployment
metadata: { name: mf-projector-compute }
spec:
  replicas: 1
  selector: { matchLabels: { app: mf-projector-compute } }
  template:
    metadata: { labels: { app: mf-projector-compute } }
    spec:
      containers:
        - name: mf-projector-compute
          image: ghcr.io/metafluent/mf-projector-compute-cfg-stable:milestone
          env:
            - { name: METAFLUENT_PUBSUB_ADAPTER_CONNECTION, value: "mf-session:8900" }

Raise replicas, or add another Deployment, for more computation throughput or resilience.

---

Use a simulator

The same as Static MDS - add the mf-eta-simulator image to feed the MDS projectors, and the compute tier derives its content from what they serve.

---

Going further

• Static MDS - the base deployment this extends.
• Fine-Grained - run each service separately.
• Scalable MDS - let the projector and compute tiers grow and shrink with load automatically.
• Serving real, entitled Refinitiv data? See Configure DACS to turn on authentication and entitlement checks.

---

Where to go next

• Confirm it's running - check every component's health once the deployment is up.
• Architecture: Advanced - the projector tier as a compute node.
• Image Catalog - the compute image and its libraries.
• Deployment: Without Docker - the conventional install mechanics in full.
• Configuration: Basics - what the configuration you supply contains.
