A change feed processor must react to new and updated items in a container. What else does it need?
- A A lease container to store its progress (correct answer)
- B A Service Bus queue to store checkpoints
- C Strong consistency on the account
- D A stored procedure that copies each change
Shortcut: Change feed processor = monitored container + lease container. It doesn't need Service Bus, a particular consistency level or stored procedures. In the default latest-version mode, deletes aren't delivered.
The change feed processor keeps its checkpoints and partition leases in a separate lease container, which also lets several instances share the work. It doesn't need Service Bus, a particular consistency level or stored procedures. In the default latest-version mode, deletes aren't delivered.
