Exploring the Simplified Callback Interface for gRPC in C++

The article discusses the async callback interface for gRPC in C++. The author highlights that the traditional async API requires a lot of boilerplate code and can be complex to implement. However, there is a newer callback interface available that simplifies the implementation process. The callback interface is also async and allows developers to override one method for each RPC in their interface. Although the gRPC C++ landing page does not mention this interface, the author believes it is a better starting point for most projects. The callback interface provides a radical simplification and eliminates the need to deal with low-level threading models and event loops. The article also mentions that the gRPC team has accumulated experience from various projects, resulting in better performance and resource utilization. The author hopes that the gRPC team will promote the callback interface more prominently to C++ developers. Overall, using the callback interface makes it easier to choose gRPC for inter-service or inter-system communication in C++ projects.
