Reactive programming is not a new thing. Thanks to reactivex and rx-java it's a reality for almost 10 years. There are other implementations like Project Reactor  and even Vert.x . However, for Databases, we are still not there. Some databases have better support than others like Cassandra and Redis have decent support in drivers but JDBC and JPA are not quite there yet. Hibernate just went reactive. There is a hibernate-reactive project now(still beta 1.0) but looking promising. So today I want to share some simple POC I made to make Hibernate Reactive work with Spring Boot 2.x using webflux: using Netty of course. So I made a video going throught the code and explaining how it works. I personally worked with all sorts of persistence on the last +17 years on technology but not an ORM fan nowadays. However I always appreciate performance and better APIs, so I think this is promising even if is for legacy application modernization.

Akka-Streams is one of the many interesting and very useful Akka modules. Akka is a powerful actor / reactive framework for the JVM. Akka is an extremely high-performance library -- you can do Up to 50 million msg/sec on a single machine. Small memory footprint; ~2.5 million actors per GB of the heap. Akka is also resilient by Design and follows the principles of the Reactive Manifesto . Akka follows Erlang Actor philosophy/ideas.  Many big and successful companies use Akka in production like Blizzard, Intel, Wallmart, Paypal, Amazon, Zalando, Netflix, IGN, VMware UBS, and much many more others.

Unfortunately, FP is a religious suggest for a lot of people. I jumped on the FP Religious bandwagon for awhile back into 2012. Today I consider myself more practical rather than just "pure" in regards of FP. To be 100% clear my goal is not to be controversial or create any kind of flamewar. I feel free to disagree with me. The fact is I like Scala a lot and is very hard to talk about java 8 without talking about Scala. IMHO Java 8 got some good influence from Scala. IMHO I don't think Java 8 is a drug to get into Haskell :-). Java 8 got some sort of FP influence, Thanks to Scala I would say. I suppose to deliver a talk about functional and reactive programming with Java 8, 2 years ago and I found this slide deck in my machine so I thought about making a video presenting some of the functional programming principles with Java 8 including frameworks such as RxJava. So this is a ~40 minutes video - I hope you guys enjoy and have fun.
