Understanding and implementing asynchronous patterns in a minimal API
The opening pizza analogy is hopefully a good, high-level illustration of the difference between asynchronous and synchronous programming. Asynchronous programming is significant in minimal APIs because it provides a lot of flexibility for managing the conversations between client and server. It is particularly beneficial to long-running operations, where the overall performance of a request would be compromised by operations running in a linear fashion, with each operation blocking the other.
Asynchronous programming also provides scalability benefits, allowing APIs to cope with high demand. This is achieved by ensuring that threads are not blocked. Operations in an asynchronous endpoint can register callbacks to ensure that the execution thread can continue running other tasks until that callback is resolved. This brings with it other resource benefits such as better management of the thread pool, lower CPU...
