// When the `list` query parameter is provided (its value is ignored), the

// The (repeatable) `buckets` query parameter is a list of bucket names (or it

* SQLite
* Oracle
* Microsoft SQL Server, etc.

In this example, we'll use **SQLite**, because it uses a single file and Python has integrated support. So, you can copy this example and run it as is.

Later, for your production application, you might want to use a database server like **PostgreSQL**.

### Events with Failures

When an operation fails, a failure method is called. This is `connectFailed()` for failures while building a connection to the server, and `callFailed()` when the HTTP call fails permanently. When a failure happens it is possible that a `start` event won’t have a corresponding `end` event.

Der wesentliche Punkt ist, dass der `sub`-Schlüssel in der gesamten Anwendung eine eindeutige Kennung haben sollte, und er sollte ein String sein.

## Es testen

Führen Sie den Server aus und gehen Sie zur Dokumentation: <a href="http://127.0.0.1:8000/docs" class="external-link" target="_blank">http://127.0.0.1:8000/docs</a>.

    } else {
      serverNoContextTakeover // Server is deflating.
    }
