問題文
A nightly job must pick up files that a partner drops onto an FTP server. Which connector element makes the application react to the arrival of a new file without a separate Scheduler being added to the flow?
選択肢
- The Read operation with a wildcard path, which returns each matching file as a separate Mule event so that the flow is executed once for every file that matches the pattern at the moment the operation runs.
- The connector's listener, which polls the configured directory on its own schedule and starts one flow execution per file it finds.
- The List operation, which blocks until a file appears and then returns it, so the flow can be started once and left waiting for the partner.
- The connector configuration's reconnection strategy.
