Producers and consumers
Apache Kafka® is a distributed system for exchanging messages between data producers and consumers.
- Consumer is a data source application. It connects to an Apache Kafka® cluster and writes messages with data to specific topics and their partitions. To be able to write messages to a topic or partition, the application must have a user account with the appropriate set of permissions.
- Consumer is an application that receives and processes data from producers. Instead of getting data directly from a producer, it connects to the Apache Kafka® cluster, subscribes to certain topics, and reads messages from them. To be able to subscribe to a topic, the application must have a user account with the appropriate set of permissions.
