Project Reactor by Example

The talk will include an explanation of asynchronous non-blocking programming with code snippets. It will demonstrate how asynchronous non-blocking code helps with resource utilization, isolation beyond just performing I/O in parallel and show how it can be measured/benchmarked. I will present a quick primer on reactive programming. Using a scenario where we need to fetch data from different microservices, we will solve it by leveraging reactive operators to combine different sources of data, perform non-blocking I/O, exception handling, retries, fallbacks and explain how work is scheduled on different threads. Finally, we will go over common mistakes and gotchas with project reactor.
