- This skill should be used when the user asks to work with Modal.com persistence or shared state. PROACTIVELY activate for:
- Modal Volumes, vol.commit, Dict, Queue, CloudBucketMount, S3 or GCS mounts, secret-backed storage credentials, model cache persistence, dataset staging, shared queues, distributed state, volume consistency, and storage troubleshooting.
- Provides:
- storage primitive selection matrix, commit/consistency patterns, mount configuration recipes, and troubleshooting checklists.
Modal Storage Knowledge
Use this skill for Modal persistence and shared-state primitives. For compute, GPU, autoscaling, or deployment topics, use modal-compute:modal-compute-knowledge.
Quick routing
- Volumes: durable filesystem state mounted into functions/classes; call
vol.commit()after writes that must persist. - Dict: distributed key-value state for small shared metadata, caches, and coordination.
- Queue: producer/consumer task handoff and distributed job queues.
- CloudBucketMount: direct access to S3/GCS-compatible object storage through Modal mounts.
- Secrets: use named secrets for storage credentials; never hardcode keys.
Essential workflow
- Identify whether the workload needs filesystem semantics, key-value state, queueing, or object-store access.
- Mount the storage primitive explicitly on every function/class that needs it.
- For Volumes, commit after writes and reload/read carefully across concurrent workers.
- Keep credentials in Modal Secrets and scope them to the functions that require access.
- Validate with a small read/write/delete test before scaling parallel jobs.
Detailed reference
