feat(serverv2): integrate gRPC #21038
Conversation
WalkthroughWalkthroughThe changes present a significant refactor of gRPC method handling in the application, simplifying the interface by removing the need for byte slice inputs in decoding functions. Key methods and structures were renamed to reflect this streamlined approach, enhancing code clarity and maintainability while improving the functionality associated with gRPC interactions. Changes

Improve error handling and optimize getServices method.
The getServices method is well-structured but can be improved by handling errors more effectively and optimizing the conversion of method names.
- for _, methodName := range methods {
- methodName = strings.Join(strings.Split(methodName[1:], "/"), ".")
+ for _, method := range methods {
+ methodName := strings.ReplaceAll(method[1:], "/", ".")Additionally, consider logging the successful retrieval of method descriptors for better traceability.
+ s.log.Info("successfully retrieved method descriptor", "method", methodName)

Correct the typo in the method name.
The method name should be GetGRPCMethodsToMessageMap instead of GetGPRCMethodsToMessageMap.

‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.
