Redis

In this guide, you'll learn about the managed Redis service that Medusa provides as part of your project environments.

Managed Redis Service#

Medusa provisions and manages Redis servers for each of your environments.

Each project environment has a dedicated Redis server. These Redis servers are entirely isolated from one another, similar to the Postgres databases.

Configured Redis Infrastructure Modules#

Medusa automatically configures your Medusa application to use Redis-based Infrastructure Modules, including:

• Redis Event Module
• Redis Cache Module
• Redis Locking Module Provider
• Redis Workflow Engine Module

So, you don't need to configure any of these modules and providers or set up Redis manually. Also, if you have them configured in medusa-config.ts, remove them to avoid conflicts.

Access Redis Configurations#

Since Cloud is a managed service, you can't directly access your Redis instance or its configurations. Medusa also doesn't expose the Redis instance connection or configuration details.

Override Redis Configurations#

If you need to customize the Redis configurations for any of the Redis modules and providers, you must host and manage your own Redis instance externally.

Then, configure the modules and providers you're overriding in your medusa-config.ts file to connect to your external Redis instance. Refer to the documentation for each module for more details on how to configure it.
