A violet-dell processor cannot keep up on a single ordered log in Event Hubs. Why do partitions exist for that workload?
Select an answer to reveal the explanation.
Short Explanation
One partition, one ordered pipe. Add partitions so consumers can fan out—your parallelism ceiling per consumer group is that partition count.
Full Explanation
Event Hubs partitions enable parallel consumption: each consumer group can assign readers across partitions, and partition count is the parallelism ceiling for that group. They are not ARM stores, not “always free” capacity, and they do not replace retention by instant deletion.
