The HandlerFunction is a function that takes ServerRequest and returns delayed ServerResponse. Handling Errors in Spring WebFlux | Baeldung When a request comes from another microservice we can track those using a tracing id. Spans can be started and stopped, and they keep track of their timing information. In Spring Boot, if we call one service/module to another using Feign client we can see an X-B3-TraceId in the header which basically tracks the call traversing in a single request-response cycle.

I hope this blog will help someone, someday. It supports the back pressure concept and uses Netty as the inbuilt server to run reactive applications. Basically, it is a way of adding behavior to existing code without modifying that code. Reactive programming involves modeling data and events as observable data streams and implementing data processing routines to react to the changes in those streams. It is built around publisher-subscriber pattern (observer pattern). Click generate to download the startup project files as a zip. It is not great for developing traditional CRUD applications. Find centralized, trusted content and collaborate around the technologies you use most. Webflux is the non-blocking thing, thus a single request can go through multiple threads that are not blocked for a single request, rather serving several requests concurrently. Spring WebFlux provides thread pool abstractions called Schedulers. A publisher can serve multiple subscribers. The example applications use Spring Boot, so we can add to our project a starter which enables OpenTracing/Jaeger without doing so much. It should be better if we move this request body log to a common area. Our goal was to design a microservice which could handle many concurrent connections. It supports the back pressure concept and uses Netty as the inbuilt server to run reactive applications. Are you sure you want to hide this comment?
