11:10, is there any way to pass array of movie Ids and get the response in a single go? Iterative connections to the REST API can be costly.

Please use white the board, I'm unable to identify the code with the current black screen. Thanks

[noranafari]

I'm actually learning many things besides microservices. <3

Thanks so much for this priceless work of yours in educating us. However, I have a question. Instead creating constructor why can't we add annotation @component to bean and use the object in controller?

[CoolCoder]

So glad to see this video, just save me for one problem about feign call

[arnoclaude]

Sir Thanks for uploading these tutorials. Sir at time 8:45 question was about to how about using abstract classes or interfaces and sharing these between microservices? your answer was good but i want to add one thing more in your answer (Microservices architecture being used as loosely coupled between each service component. if we uses abstract classes and interfaces then this approach will be drive to tight coupling). Correct me if i am wrong.
