In this chapter, we learned about future developments in the MicroProfile specification with the Long Running Actions, Context Propagation, and GraphQL projects outside the umbrella release, and the Boost project that's still in the MicroProfile sandbox. In addition, you learned about reactive messaging concepts, the MicroProfile reactive messaging architecture, and how to implement reactive microservices using Eclipse MicroProfile reactive constructs via code examples. You also gained some knowledge of the background of each of these projects, their capabilities, annotations, and code examples when applicable, as well as their current state. Lastly, we presented the relationship between two similar but different projects: Eclipse MicroProfile and Jakarta EE, and discussed how their possible relationship could evolve in the future.
In the next chapter, we will learn...
