In the world of cloud-native apps, we need to deal with a large amount of data from multiple sources. This requires considerable effort to read, process, and distribute. As the number of records increases, plain Java may not be the best solution.

We discuss this universe and its architecture and templates—providing live code examples to demonstrate all possibilities you have on your hands.
