### Feature Gates

| Name | Default Value | Description |
|--------------------------------|---------------|-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|
| `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). |
| `DisableFailFastBehavior` | `false` | Controls whether the fail-fast behavior when waiting for resources to become ready should be disabled. |
| `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. |
| `ExternalArtifact` | `true` | Enables support for the [ExternalArtifact](https://github.com/fluxcd/source-controller/blob/main/docs/spec/v1/externalartifacts.md) source type. |
| `GroupChangeLog` | `false` | Groups together kubernetes objects in log output. Reduces cardinality for Elasticsearch/Opensearch indexing |
| `ObjectLevelWorkloadIdentity` | `false` | Enables the use of object-level workload identity for the controller. |
| `StrictPostBuildSubstitutions` | `false` | Controls whether the post-build substitutions should fail if a variable without a default value is declared in files but is missing from the input vars. |
