Visualizing Concurrent and Parallel Behavior in Project Reactor and Java Parallel Streams.

This video conducts a deep-dive into the concurrent and parallel processing mechanisms in Project Reactor, visualizing precisely how its mechanisms behave when programmed using different placements of operations like subscribeOn() and runOn(). For completeness, the behavior of Java parallel streams is also visualized, showing how the calling thread is included with threads in the common fork-join pool are used to process streams in parallel.
