+  _Note:_ This will add spans for all requests to the caches configured in Django. This will probably add some overhead to your server an also add multiple spans to your performance waterfall diagrams. If you do not want this, you can disable this feature in the DjangoIntegration:
+
+  ```python
+  sentry_sdk.init(
+      dsn="...",
+      integrations=[
+          DjangoIntegration(cache_spans=False),
+      ]
+  )
+  ```
