How to connect to Kafka, create a new topic, and set up Kafka producer and consumer using Java Spring Boot in CodeNOW. Ensure that you either have a running Kafka cluster or you can use the docker-compose.Yml file to spin up a local Kafka cluster. In the Confluent Cloud Console, navigate to the RawBiometricsImported topic and open the Messages tab. There are 3 microservices, when a user created via user-service that service insert a record onto user table(postgre) and it produce an event to user_service. I am trying to understand how Kafka can be used for real time notification. Let's say I have a kafka topic for alerting purposes. Kafka is a distributed system consisting of servers and clients that communicate via a high-performance TCP network protocol. You can use the Apache Kafka trigger in Azure Functions to run your function code in response to messages in Kafka topics. This integration includes 14 useful alerts and 7 pre-built dashboards to help monitor and visualize Kafka metrics and logs.
