In this post I will show how to build simple data-enriching pipeline using Kotlin coroutines. I will use Channels and Actors abstractions provided by kotlinx-coroutines. In Actors model «actors» are the universal primitives of concurrent computation. In response to a message that it receives, an actor can: make local decisions, create more actors, send more messages, and determine how to respond to the next message received. Actors may modify their own private state, but can only affect each other through messages (avoiding the need for any locks).

Defining error format is important part of REST API design.

Spring-Boot and Spring Security provide pretty nice error handling for RESTful APIs out of the box. Although it has to be documented, especially when contract-first approach to API design is used.

It is good idea to follow some common format for error responses. But OAuth2 specification and Spring Boot format may not satisfy those requirements.
