Along with brokers, topics, and consumers, producers are one of the essential components of a Redpanda deployment. Within streaming applications, producers are responsible for sending data to brokers, where the data is stored in topics made up of partitions.
When a producer writes messages to a topic, each message should be recorded only once in the order in which it was sent. However, network issues such as a connection failure can result in a timeout, which prevents a write request from succeeding. Idempotent producers prevent this problem by assigning a unique ID to every write request.
