Got answer to the question I had asked in the 5th part of the series where we compared CompletablFuture approach's performance to that of the Mono approach. lol I had this think in mind that the wait is still happening somewhere in the framework, so why would returning a Mono be more efficient. Understood to some extent in this video. Thanks.

i got my "click✨" moment on this lecture, thanks! never thought netty was this powerful.

Thank you sir for your nice explanation

Reactive gives maximum performance (throughput) if the tasks are I/O intensive. However, if the tasks are CPU intensive, the throughput is still low and we will eventually run out of threads!

I’m the first one who liked the video. We appreciate the offer you’re putting there man.

Is reactive approach really usefull in the case of hard calculations? I think it's usefull when dealing with slow IO or waiting for reply from another system. So the thread could do something at this time and not just be blocked. But in the case of calculationg fibonacci numbers, the thread is busy anyway, it can't jump to another block of code and do smth.

Does the CachedThreadPool that exists in Java for ages implements the same idea of reactivity? If it's so what is really new about all that reactivity staff and Netty server? And is Netty indeed server like Tomcat that is web server processing web requests based on Servlets specification or is it just another concurrency framework?

09:14 if you are doing rate control (I mean telling request 1 ) after some condition fulfilled , but there are items sent more , say 5 in that period , what would happen ?

Can we test the reactive nature of our developed services?

[@techfan1017]

yes of course
