Memql

memQL

AI-native time-series memory graph with a single DSL. Unifies concepts, queries, agent workflows, and voice into deployable primitives.

Designed and built with Claude as co-author.

> Status: Alpha / pre-1.0 — not production-ready. memQL is under active development. The DSL, engine API, and wire surface are still evolving; expect breaking changes between commits. Suitable for experimentation, prototyping, and early-design feedback today.

What is memQL?

memQL is a distributed time-series memory graph with its own DSL — a single language for declaring concepts (schemas), queries, mutations, tools, and event-driven automations side-by-side, then executing them across specialized nodes.

It replaces the integration glue AI-native teams typically hand-write — vector store + workflow engine + AI gateway + voice stack — with one deployable primitive. A team that would otherwise stitch together four systems can declare an agent's memory, behavior, and triggers in one DSL file and run them on a memQL cluster.

Why memQL?

Agent and voice deployments today are integration-heavy. Most of the engineering effort is plumbing — keeping state consistent across a vector store, an orchestrator, a tool registry, and a model provider. memQL collapses that plumbing: concepts and queries live in the same place; tools, automations, and workflows reference them directly; the engine handles consistency, time-series storage, and execution.

Example

@version("1.0.0")
@namespace("acme")
concept ticket {
  subject     string   @required
  priority    string   @default("normal")
  status      enum("open", "closed") @default("open")
}

@enabled
@handler(type="query", query="concept==v1:acme:ticket && payload.priority==\"$args.priority\"")
@executionTime("fast")
@description("List tickets by priority")
tool listByPriority {
  priority string @required
}

A concept (schema) and an LLM-callable tool in the same file, same language. Add queries, mutations, or event-driven automations right next to them.

Development

Prerequisites

Hardware:

• macOS with Apple Silicon (M1/M2/M3)
• MacBook Pro or MacBook Air
• 16GB RAM minimum (32GB recommended)

Software:

• Go 1.26.1+ (ARM64 build)
• Docker Desktop for Mac (Apple Silicon)
• k3d + kubectl (brew install k3d kubectl)
• Azure CLI (az) — for staging/prod deploys
• git

Local Development Workflow

1. Clone repository

``bash git clone https://github.com/znasllc-io/memql.git cd memql ``

1. Start the local cluster

``bash make up ``

1. Make changes and test

```bash # Edit code # ...

# Rebuild + reload the changed node into k3d make dev

# Run tests go test ./...

# View logs kubectl logs -n memql deploy/bff -f ```

1. Deploy to staging for integration testing

``bash make deploy VERSION=X ``

1. Commit to main (focused commits) or open a feature branch + PR

when review is genuinely useful. Stage by explicit path: ``bash git add path/to/changed.file git commit -m "domain: imperative subject" git push origin main ``

# Bootstrap (cluster + ArgoCD + seeded secrets)
make up

# View pod logs
kubectl logs -n memql deploy/bff -f

# Access database (via the k3d postgres port-forward)
psql postgres://memql:memql_dev@localhost:5432/memql

MemQL Language

MemQL DSL is a domain-specific query language for time-series memory graphs.

Example Query

// Find active human participants in a space
queryActiveHumanParticipants({
  "spaceId": "space_123"
})

Example Automation

@enabled
@trigger(event="node.created", concept="v1:cognition:space", partition="*")
@description("On space creation, auto-join the creator's assistant")
automation autoJoinSI {
  step run {
    logic autoJoinSI { event: event }
  }
}

Deployment

memQL runs on Azure Kubernetes Service (AKS). Deploy to staging with make deploy VERSION=X (scripts/deploy/aks-deploy.sh); production promotes a validated version.

See the product pack repo's docs/operate/deployment-strategy.md for deploy/topology (cluster aks-memql-staging, ACR acrmemql.azurecr.io, Tiger Cloud DB, the migration + smoke gates, and the staging → prod promotion flow).

Contributing

1. Read [docs/public/overview/tech-stack.md](docs/public/overview/tech-stack.md)
2. Make changes and test in development environment (go test ./...)
3. Deploy to staging for integration testing
4. Commit directly to main for focused changes, or open a PR when review is useful
5. Stage files by explicit path (git add )

Git workflow: Single long-lived main branch. Pre-release: no backwards-compat shims; fix both memQL and the consumer at once.
