all great questions!

[@hegdevishwa]

Thanks for the great tutorials as always!! You make things very easy to understand. I have one question on async. Have you come across any use case so far where you have used or had to use async instead of sync? If yes could you please briefly explain the scenario and why it was chosen over sycn?

I am just sharing my exp with you on this, I worked on E-learning platform where we need to integrate the external courses to our LMS(Learning Management System). So students have to learn that course and do the assignment in same course. Here returning grade(score) to student is not an synchronize since Assignment can have essay questions where instructor has to check and give the score later. This score will reside in third party service since this course is from externally. In that case doing the course is synchronize but grade sharing is a Asynchronize. In order to take these Async score data we can have several ways like MQ or third part can send those to a service endpoints which is shared early(LTI concepts).

May I ask if now people use retrofit instead of all the build-in rest Http dependencies?

[@sanjin1458]

How about Flux in WebClient ?

[@satyamsanghi]

Hi, can't we create a list of users with their movie id in Movie Catalog Service? After that make an API call for each movie id in this list to Movie Info Service for a movie name and Rating Service to get Rating for that each movie Id?

[@JENISONGRACIOUS]

How does asynchronous make a difference here. Any how the master service that calls the other microservices has to wait until all the responses arrive and so we have4 to block the thread in the master api. So what advantage does this asyncronous call have

[@dipanshukhatri9205]

when to call rest service through rest template and when to call through feign client

[@vaibhav12jain]

Can you please provide source code link you are using ?

[@soumikgenious]

another way to call rest service is fein client? That is also sychronous right?

[@narasimhareddy3087]

how can we manage session Management in microservices

[@ZtowhyA]

return Callable for async api

[@shivraj777]

Lets say we have microservice entry point class A, it has RestController R, Service S and Repository P. Database is MySql. Server Tomcat. (tomcat default is 200 threads) Service performs some crud operations. Question 1: Lets say we have lot of threads trying to access save method in Service. How do I make sure it is threadsafe? Meaning no two threads at the same time shouldn’t try to insert same record twice. Question 2: Is there any specific way we can make microservice threadsafe specially when its performing CRUD operation?

[@farazgulzar7688]

why dont you use generic response instead of returning all explicity type of responses !!

[@luthfullahhillkabir1361]

pls give your sorce code

[@AshishSuwalka]

Can You help us making an API using which we could LIKE ALL OF YOUR TUTORIALS on KZbin? :D Great explanation Information about every little doubt anyone can have.. As I always comment on your tutorials, #NoOneExplainsBetterThanYou

[@smithdragon6477]

hey teacher can u teach me microservice transaction management

[@sairammullapudi6658]

Why you are using default constructors when there is some error

[@gurupreetsingh8347]

resttamplate is not a thread safe java brain sir.,, ji

[@karthikeyan1996_]

The instructor is very genius. But the audience are constantly asking most dumb questions. For example first question is are both these calls asynchronous, from the start itself it was communicated getForObject uses synchronous calls blocking calls. Webclient is recent one which use async way which can be like a promise. Was he sleeping during whole lecture. Bunch of noobs in the audience who never even have any idea of spring or java or general backend development
