Spring WebFlux enables non-blocking, reactive HTTP handling. It solves a specific problem — high-concurrency I/O-bound services — and creates new problems for everything else. Here is what it actually does and the honest case for when it's worth adopting.
Read moreEvery endpoint is a permanent contract the moment a client integrates against it. API surface area grows easily and shrinks painfully. Here is how to keep it smaller from the start and how to reduce it when it has already grown.
