In this section, we will walk through different Kafka producer components, and at a higher level, cover how messages get transferred from a Kafka producer application to Kafka queues. While writing producer applications, you generally use Producer APIs, which expose methods at a very abstract level. Before sending any data, a lot of steps are performed by these APIs.
