Production Readiness

Copy Markdown View Source

Squid Mesh provides a supported 0.1.x journal runtime for embedded host-app workflows.

Production adoption should still be treated as an application-owned integration: choose a queue/leasing strategy, run the host-app verification paths, and keep operational ownership explicit. The goal is to keep the public contract aligned with the verification that has actually been run.

Current Status

What exists today:

  • durable workflow runtime on top of Postgres-backed Jido journals and host-supervised execute_next/1 workers
  • replay, cancellation, retries, cron activation, and inspection
  • example host app harness with smoke, cancellation, restart resilience, and soak/load entrypoints
  • paused-run resume semantics now verified across restart boundaries in the example host app
  • explicit recovery and operational boundaries in the docs

What remains application-owned:

  • support is still defined from a narrow verified baseline
  • soak/load validation is bounded verification, not long-term operational evidence
  • broader dogfooding and real production adoption history still matter

Readiness Checklist

Before broader production rollout, each host app should have:

  • a documented supported baseline for the current release line
  • a production operations guide
  • restart and deploy resilience verification
  • soak/load validation on the journal-backed runtime
  • no known unresolved correctness bug in the core runtime
  • at least one round of host-app dogfooding under normal deploy workflows

Example Verification Entry Points

The example host app provides the repeatable checks:

cd examples/minimal_host_app
MIX_ENV=test mix example.smoke
MIX_ENV=test mix example.resilience
MIX_ENV=test mix example.soak

These checks are meant to answer different questions:

  • example.smoke: does the basic embedded workflow path work?
  • example.resilience: do queued, delayed, retrying, and paused-then-resumed runs survive worker and scheduler restart boundaries?
  • example.soak: does the runtime remain stable under a bounded mix of success, retry, replay, and cancellation traffic?

Decision Rule

Adopt Squid Mesh in production only when:

  1. the checklist above is complete for the host app,
  2. the verification paths are green on the supported baseline,
  3. the team is ready to own the documented queue, lease, retry, and operations boundaries.

For initial rollout, prefer a bounded workflow class with clear operator inspection needs and well-understood side effects.
