but it cannot maintain order between multiple partitions.) For example, suppose 4 events come in this order: E1 → E2 → E3 → E4. If they go into the same partition, they will always be read in the same order: �� E1 → E2 → E3 → E4 ✅ But if they go into different partitions, the reading order may change depending on processing speed. For example: �� Partition 0 → E1, E3 �� Partition 1 → E2, E4 Now consumers may read: �� E1 → E2 → E3 → E4 (or sometimes different order) To control where events go, a partition key can be used. Events with the same partition key always go to the same partition, which helps maintain order for related data. How Partition is Created (Event Hub):- In Azure Event Hub, partitions are created at the time of Event Hub creation. When you create an Event Hub in Azure, you must choose the number of partitions (for example: 2, 4, 8, etc.). These partitions are fixed for that Event Hub and cannot be changed later (in standard setup). Once partitions are created, Event Hub automatically distributes incoming events across them. If a partition key is provided by the producer, Event Hub sends all related events to the same partition to maintain order. If no partition key is given, Event Hub distributes events automatically (round-robin style) across partitions. Partitions are created mainly to support scalability and parallel processing. Each partition acts like an independent log where events are stored in sequence.
