# Version 1.20.4

This version introduces Worker Mode to start Medusa instances for background job execution separate from the main application process.

## Highlights

### Introducing Worker Mode

This release ships Worker Mode, a new runtime mode for Medusa instances.

Worker Mode allows you to start a Medusa instance in a process separate from the main application process. An instance running in Worker Mode is useful for executing long-running or resource-heavy tasks in the background. Those tasks are offloaded to a separate process and will not affect the performance of the main application. Examples of tasks are importing data or updating a search index. While Worker Mode is especially good for resource-intensive tasks, we recommend always starting an instance in this mode if possible. 

Worker Mode introduces three new runtime modes for your Medusa instance:
- `server`: API Routes are registered, and no workers are started.
- `worker`: API Routes are not registered, and workers are started.
- `shared`: API routes are registered, and workers are started (the regular runtime mode + default).

The worker mode is configured in `medusa-config.js`:
```ts
// medusa-config.js
const projectConfig = {
  ...,
  database_url: "...",
  worker_mode: "worker",
};
```

In this release, the Redis Event Bus has been updated to leverage the worker architecture. Instantiating a Medusa instance with `worker_mode: "server"` and a different one with `worker_mode: "worker"` will separate background job processing from the public-facing main application, given that the Redis Event Bus module is installed.
