WHY ADAPT? - When writing new projects - When moving
to Java 9 - When you want to use Spring 5 - When you want to use Kotlin
WHY REACTIVE? - When real time or event-driven communication is
important - When processing large, or infinite amounts of data - When you expect that there will be a large amount of traffic
WHY NOT REACTIVE? - When expected to make blocking calls
ANY QUESTIONS?* * Make sure to ask them in a
reactive way. Don’t block your brains when you’re waiting for an answer.
