-- Implement your own `getSecondaryResource` method on your `DependentResource` implementation from scratch.
-- Override the `selectManagedSecondaryResource` method, if your `DependentResource` extends `AbstractDependentResource`.

+- Override the `selectTargetSecondaryResource` method, if your `DependentResource` extends `AbstractDependentResource`.
   This should be relatively simple to override this method to optimize the matching to your needs. You can see an
   example of such an implementation in
   the [`ExternalWithStateDependentResource`](https://github.com/operator-framework/java-operator-sdk/blob/main/operator-framework/src/test/java/io/javaoperatorsdk/operator/dependent/externalstate/ExternalWithStateDependentResource.java)
