What does a partition in Event Hubs represent?
- A A separate namespace
- B An ordered sequence of events within the Event Hub; events are processed in order within a partition (correct answer)
- C A consumer group
- D A throughput unit
Shortcut: Each partition is an ordered, immutable log. Events with the same partition key go to the same partition, guaranteeing ordering for that key. Different partitions are processed independently and in parallel.
