-By default, there are no concurrency limits for Hatchet workflows. Workflow runs are immediately executed as soon as they are triggered (by an event, cron, or schedule). However, you can enforce a concurrency limit by decorating a custom function with `hatchet.concurrency`. This function returns a **concurrency group key**, which is a string that is used to group concurrent executions. **Note that this function should not also be used as a `hatchet.step`.** For example, the following workflow will only allow 5 concurrent executions for any workflow execution of `ConcurrencyDemoWorkflow`, since the key is statically set to `concurrency-key`:

However, you can enforce a concurrency limit by adding a `concurrency` configuration to your workflow declaration.
