Azure Event Hubs represents the "front door" for an event pipeline, often called an event ingestor in solution architectures. An event ingestor is a component or service that sits between event publishers and event consumers to decouple the production of an event stream from the consumption of those events. Event Hubs provides a unified streaming platform with time retention buffer, decoupling event producers from event consumers.
A partition is an ordered sequence of events that is held in an Event Hubs. Partitions are a means of data organization associated with the parallelism required by event consumers.
An Event Hubs client is the primary interface for developers interacting with the Event Hubs client library. There are several different Event Hub clients, each dedicated to a specific use of Event Hubs, such as publishing or consuming events.
An Event Hubs producer is a type of client that serves as a source of telemetry data, diagnostics information, usage logs, or other log data, as part of an embedded device solution, a mobile device application, a game title running on a console or other device, some client or server based business solution, or a web site.
An Event Hubs consumer is a type of client which reads information from the Event Hub and allows processing of it.
A consumer group is a view of an entire Event Hubs. Consumer groups enable multiple consuming applications to each have a separate view of the event stream, and to read the stream independently at their own pace and from their own position.
Event receivers: Any entity that reads event data from an Event Hubs. All Event Hubs consumers connect via the AMQP 1.0 session. The Event Hubs service delivers events through a session as they become available. All Kafka consumers connect via the Kafka protocol 1.0 and later.
Throughput units or processing units: Pre-purchased units of capacity that control the throughput capacity of Event Hubs.
