# Redis™ Command Support

Explanation of Invar's Redis™ command compatibility

Invar aims for broad compatibility with the Redis command set as of Redis 6.2, with two provisos:

* A command has to be feasible on the underlying LSM store without compromising its behavior — generally, that means it needs to keep roughly the same time/space complexity it has in Redis, not silently become something much slower.
* A command has to make semantic sense for Invar. Cluster management commands, for instance, don't — there's no cluster to manage in a single-writer model.

Remember: Invar's goal is not to be a 100% drop-in replacement for Redis™. Invar is a durable, transactional document store which speaks the RESP wire protocol and supports a wide variety of standard Redis™ commands.

Real-world client compatibility (BullMQ in particular) is the practical target this table gets tested against, not just the spec.

## Not on the roadmap

A few entire command groups aren't gaps so much as deliberate non-goals, and are worth naming up front rather than leaving you to infer it from a long list of 🚫:

* **Geospatial** — a large ongoing maintenance surface for a use case that hasn't come up yet.
* **Cluster management** — doesn't map onto Invar's single-node, single-writer model.
* **RBAC / ACL / AUTH** — authentication and authorization are explicitly out of scope for Invar itself. If you need this, see [Hardpoint's managed options](https://hardpoint.dev/).

**Legend:** ✅ implemented · 🚧 not yet implemented · 🚫 no plan to implement

Entire command groups with no support yet, but not ruled out, are simply omitted below rather than listed as all-🚧.

## Pub/Sub commands

Like Redis, Pub/Sub messages sent through Invar are **not persisted** — they exist in memory only, and aren't covered by transactional guarantees. Treat Pub/Sub as best-effort, same as you would with real Redis.
