gRPC is faster by avoiding heavy serialisation mechanisms like json and xml parser uses.. there are other alternatives of proto3 which uses better memory allocation and compression… gRPC is fast, but it is really tough to replace rest bcz of its flexibility on schema modifications ..
It is almost like SOAP webservices. Instead of WSDL file, writing protobuf file & generating classes. As it has binary protocol, if spring has, spring native app with grpc support & reactive, that is crazy combination with respect to performance. Agree?
Good video 👍. You mentioned that you are using M1 macbook. Can you please let me know if it is pro or air and also have you faced any issues related to programming I mean with any installations(java, maven, docker etc) on M1 laptops?
There have to be so many controller annotations required. Unless big players won't be interested in this, it will be another communication way like Corba and Rmi.
Nice explanation. So we can't test service in postman or browser? It is bit extra effort when compared with rest api's. In industry, people are using extensively?
Hi, thanks for this video! I am super stumped on how exactly do I implement client stubs with this library in spring boot. I fail to inject them properly, would be super thankful for a demonstration.
Hi Ajay, Very informative video. We can also use bloom RPC ( like postman for rest) to test instead of grpcurl. Could you also explain unary, client streaming, server streaming, bidirectional calls as well
I think: - unary: client send one request and server will respond one response. - client streaming: client send a stream of messages and server will respond one response - server streaming: client send one request and server will respond a stream of message - bidirectional stream: client send a stream of messages and server will respond a stream of messages
Really good video that got me started on gRPC for Spring Boot. Curious, anyone knows the helpful terminal utility that shows the command parameters (see video time 25:32)?

In the plugin configuration, use the below xml. I hardcoded to osx since grpc doesnt have compiler for m1 chips yet. com.google.protobuf:protoc:3.4.0:exe:${os.detected.classifier}
@@TechPrimers cool, it worked for me now.... just needed to change the hardcoded part - for windows its like - io.grpc:protoc-gen-grpc-java:${grpc.version}:exe:${os.detected.classifier}
You won't believe it, but your videos saved my life! Keep up the good work
Glad they are helpful Lau Wei.
Thanks for a clear and short explanation.
Very good video to start learning gRPC
Simply the best way to understand and implement Grpc. Thanks Sir
Very useful and pragmatic crash course on grpc, thanks!
I was about to start series on gRPC and micro services and I saw your video. Keep it up. 👍👍❤️

good video. keep it on. some suggestion, maybe you can demonstrate a comparison of how grpc is faster than rest protocol.
Great video, would be really helpful for learning grpc for Java guys.

Thanks for the video man, really appreciate it.
Great Intro to gRPC!!! Can you compare gRPC with RSocket? Which one is better? Thank you.
Nice explanation, Could you please do for Gradle project .
Bi directional streaming is required for this particular video session.
Thanks for this excellent video.
There have to be so many controller annotations required. Unless big players won't be interested in this, it will be another communication way like Corba and Rmi.
Could you please make a video using spring security in gRPC based microservices and also use spring data jpa for persistence
Great video. Any idea on the client side implementation? For java service to service communication?
Nice explanation.
So we can't test service in postman or browser?
It is bit extra effort when compared with rest api's.
In industry, people are using extensively?
nice spring initializer!!
Thanks🎉
Great explanation, Thanks for this.
Great job on this
Hi ,could you please make a video with spring webflux with grpc...Thanks in advance
please make video on Grpc test cases
Very good video!!!!

Thank you so much
Sir, Thanks for the video. I have a question, how can we call one service from another as we do with RestTemplate

I think:
- unary: client send one request and server will respond one response.

Good one...thanks !
What is difference between gRPC and REST?
can you update your github file to match with the result of this video. So much things in pom files that are different.

Hi John. Here is the iterm setup steps which i have documented in my Github repo github.com/TechPrimers/iterm2-setup
Why not use use Vertx instead of Spring ?
Thanks a lot man...Love From pakistan
How to differentiate get and post methods in GRPC?
Hey! I'm getting this error in the greeting parent pom.xml - 'packaging' with value 'jar' is invalid. Aggregator projects require 'pom' as packaging.
sir can you suggest website where i can springboot in deep
How can we handle timeouts in grp call? Can we use resilience4j?
Thank you, interesting.
Followed instructions and does not work, so I cloned the repo and still does not work..
Would, in a real world example, each service have another service as a dependency in their pom.xml?
Depends on the repo setup. Some companies use mono repo some don’t
I thought the whole development was with command line and vi. Another command line reptile
...anyone tried this with spring-boot3? It's not starting my grpc server, but it's starting spring-boot on port 8080
osx-x86_64 can be replaced with ${os.detected.classifier} for auto detection
Thx
How do I change the port to listen to some other one since Prometheus is listening on 9090
There is a spring boot property called server.port. take a look at that
@@TechPrimers sir it didn't work. Tried using yml file too. BTW I am using Mac M1
@@TechPrimers grpc.server.port is the property where u can provide a different port number
