Sarama is a Go client library for producing and consuming messages from Apache Kafka clusters. It provides dedicated interfaces for a message producer to send typed data packets and a message consumer to read and process continuous data streams from Kafka topics.
The library includes a mocking framework and simulation layer that mimics Kafka broker behavior. These tools allow for the testing of client applications and messaging logic without requiring a live cluster.
The project handles cluster connectivity and integration through the implementation of the Kafka binary protocol over TCP. It covers the management of cluster metadata, partition state, and asynchronous event production.
