The ingestion pipeline must react to catalogue changes without polling. Which TWO facts about the change feed apply?

1. ✓ A It provides an ordered record of inserts and updates per logical partition (correct answer)
2. ✓ B A second consumer can read the same feed independently using its own lease container (correct answer)
3. C It includes deletes by default
4. D It replaces the need for a partition key
5. E It guarantees ordering across all partitions

Shortcut: The change feed is ordered within a logical partition, and separate lease containers let independent consumers read the whole feed at their own pace. Deletes are not emitted unless modelled as soft deletes with a TTL, and no cross-partition ordering guarantee exists.
