Reactor: Mastering Concurrency


Key Takeaways

1 Learn the very basics of Reactor, like `map` and `flatMap`

2 Understand what is a scheduler, when you need it and how to tune it

3 Successfully improve latency by introducing declarative concurrency

4 Troubleshoot most common mistakes and pitfalls

During the workshop, we'll learn enough of Project Reactor to run complex business logic concurrently.

No prior experience with reactive programming is required.

The workshop is an exclusive hands-on experience with no slides but 100% exercises.

I'll guide you through the details of Reactor from the very beginning.

By the end of the class, you'll know how to improve latency and throughput of your applications with a few simple patterns.
