# feature_flags

The `feature_flags` section enables or disables specific YDB features using boolean flags. To enable a feature, set the corresponding feature flag to `true` in the cluster configuration. For example, to enable support for auto-partitioning of topics in the CDC, you need to add the following lines to the configuration:

```yaml
feature_flags:
  enable_topic_autopartitioning_for_cdc: true
```
