 | `CacheSecretsAndConfigMaps` | `false`       | Configures the caching of Secrets and ConfigMaps by the controller-runtime client. When enabled, it will cache both object types, resulting in increased memory usage and cluster-wide RBAC permissions (list and watch).                                               |
 | `DisableStatusPollerCache`  | `true`        | Disables the cache of the status poller, which is used to determine the health of the resources applied by the controller. This may have a positive impact on memory usage on large clusters with many objects, at the cost of an increased number of direct API calls. |
+| `GroupChangeLog`  | `false`        | Groups together kubernetes objects in log output. Reduces cardinality for Elasticsearch/Opensearch indexing|
