hey guys! we're considering to use Micronaut+Kotlin for our backend services. For people that has used Micronaut+Kotlin in production, how were your experiences? would you choose it again if you started from scratch?

[Júlio Santos]

Hi César! How are you?
I work at iFood in Brazil, I’m doing a POC with Micronaut with Kotlin, at first it’s being really cool.

[César]

hey Julio! thanks for the reply. Have you also consider other alternatives and if so, why are you mostly interested in Micronaut?

[Júlio Santos]

Easy Cesar, we chose because the documentation is very good and we will also use gRPC

[César]

interesting, we may use grpc too. Is grpc support with Micranout better than with, say, Quarkus?

[Júlio Santos]

I don’t know if it is better, but talking to other co-workers in a big bank here in Brazil, they have chosen to use Micronaut, and the results are positive.
For this reason, we chose to perform the POC with Micronaut

[César]

thanks for your comment

[Júlio Santos]

Do you intend to perform a POC or have you already done so?

[César]

a colleague is running some POCs but on my side I'm more interested on real experiences from devs using this in production

[Júlio Santos]

I get it, next week we will perform a production load test, but at first the experience is very smooth, especially for people who have already worked with Spring.

[Júlio Santos]

What caught my attention is the deployment, it is very fast, even without using GraalVM

[César]

hey @Júlio Santos, how did the load test go?

[Júlio Santos]

We are about to apply, and when it happens I’ll tell you how it went, okay?

Hi Cesar! I know it has been a while since you posted this question. Anyways, maybe my team's experience still help you: We used micronaut+kotlin in a productive environment for 3 years. We chose it, because it promised lower memory consumption. In fact, this was a crucial point for our customer since we were running on k8s. Performance-wise Micronaut did pretty well. We were able to handle peaks of 150.000 requests / min . Kotlin's coroutines contributed to that performance obviously as well. Please let me know if you have any further question 🙂 Cheers!
