## Learn More { #learn-more }

You can learn more about **GraphQL** in the <a href="https://graphql.org/" class="external-link" target="_blank">official GraphQL documentation</a>.

Because `Annotated` can have more than one metadata annotation, you could now even use the same function with other tools, like <a href="https://typer.tiangolo.com/" class="external-link" target="_blank">Typer</a>. 🚀

## Add more validations { #add-more-validations }

You can also add a parameter `min_length`:

   * expect a newly-started thread to call [Runnable.run]. We shouldn't request new threads until
   * the already-requested ones are in service, otherwise we might create more threads than we need.
   *
   * We use [executeCallCount] and [runCallCount] to defend against starting more threads than we
   * need. Both fields are guarded by `this`.
   */
  private var executeCallCount = 0
  private var runCallCount = 0

 *
 * <p>Occasionally, an API will return a plain {@code Future} and it will be impossible to change
 * the return type. For this case, we provide a more expensive workaround in {@code
 * JdkFutureAdapters}. However, when possible, it is more efficient and reliable to create a {@code
 * ListenableFuture} directly.

| Erasure Set Size | Default Parity (EC:N) |
|------------------|-----------------------|
| 5 or fewer       |                 EC:2  |
| 6-7              |                 EC:3  |
| 8 or more        |                 EC:4  |

For more complete documentation on Erasure Set sizing, see the [MinIO Documentation on Erasure Sets](https://docs.min.io/community/minio-object-store/operations/concepts/erasure-coding.html#erasure-sets).

The `name="static"` gives it a name that can be used internally by **FastAPI**.

All these parameters can be different than "`static`", adjust them with the needs and specific details of your own application.

## More info { #more-info }

Follow below steps to enable and use AlertManager.

## Deploy and start AlertManager
Install Prometheus AlertManager from https://prometheus.io/download/ and create configuration as below

```yaml
route:

scanner               manage namespace scanning for usage calculation, lifecycle, healing and more
```

> NOTE: if you set any of the following sub-system configuration using ENVs, dynamic behavior is not supported.

### Usage scanner

<div class="termy">

```console
$ python myapp.py
```

</div>

but is not called when another file imports it, like in:

```Python
from myapp import app
```

#### More details { #more-details }

Let's say your file is named `myapp.py`.

If you run it with:

<div class="termy">

```console
$ python myapp.py
```

</div>
