PR Feedback

• 💡 General suggestions: The PR seems to be well-structured and follows good practices for Kubernetes controllers and CRDs. However, it would be beneficial to add unit tests for the new features to ensure their correctness and prevent future regressions. Additionally, it would be helpful to add more comments in the code to explain the logic and purpose of certain functions and methods, especially for complex or critical parts of the code.

• 🤖 Code feedback:

  • relevant file: controllers/model_controller.go
    suggestion: It seems like the error handling could be improved. In the Reconcile method, if the Get method returns an error other than IsNotFound, the error is returned immediately. It might be more appropriate to log the error and requeue the request, instead of stopping the reconciliation. [important]
    relevant line: if err := r.Get(ctx, req.NamespacedName, instance); err != nil {

  • relevant file: pkg/datasource/datasource.go
    suggestion: The Check method in the OSS struct could be improved by adding more specific error messages. Currently, it returns a generic error if the bucket or object does not exist. It would be more helpful to specify which one (bucket or object) does not exist in the error message. [medium]
    relevant line: if err := ds.Check(ctx, info); err != nil {

  • relevant file: controllers/model_controller.go
    suggestion: The Reconcile method could be simplified by breaking down its logic into smaller, more manageable functions. This would improve the readability and maintainability of the code. [medium]
    relevant line: func (r *ModelReconciler) Reconcile(ctx context.Context, req ctrl.Request) (ctrl.Result, error) {

  • relevant file: controllers/worker_controller.go
    suggestion: The Reconcile method in the WorkerReconciler struct is currently empty. It would be beneficial to implement the reconciliation logic or, if this is a work in progress, add a TODO comment to indicate that the implementation is pending. [important]
    relevant line: func (r *WorkerReconciler) Reconcile(ctx context.Context, req ctrl.Request) (ctrl.Result, error) {
