• kafdrop

  4 4,393 8.6 Java

  Kafka Web UI

  

  Good kafka docker setup with enclouded UI is confluent, but it's had huge images size and will download a half of world wide internet to your local pc.🤖 For this reason here as UI client i used kafdrop

• sarama

  Sarama is a Go library for Apache Kafka.

  

  For Go client in production usually used segmentio and sarama, both is good and up to you which one to chose, for this project i used segmentio. I didn't implement any interesting business logic here and didn't cover tests, because of not enough time at this moment. Our microservice can communicate by kafka, gRPC and REST.

• retry-go

  2 1,534 3.1 Go

  Simple golang library for retry mechanism

  

  Workers validate message body then call usecase, if it's returns error, try for retry, good library for retry is retry-go, if again fails, publish error message to very simple Dead Letter Queue as i said, didn't implement here any interesting business logic, so in real production we have to handle error cases in the better way. And after message success processed commit it.
