Producer
Noun · Development
Definitions
In a message queue or event-driven system, the component that creates and publishes messages or events to a broker, topic, or buffer for downstream consumers to process. The producer-consumer pattern decouples the rate and timing of data generation from its processing.
In plain English: The part of a system that creates messages or data and drops them into a queue for other parts to pick up and process.
Example: "The API server is the producer — it pushes order events to Kafka, and the fulfillment service consumes them."
