In IICS, what does the 'session recovery' feature do when a long-running mapping fails midway, and how does it affect performance design?
-
A
It re-runs the entire mapping from the beginning, so no design change is needed
-
B
It resumes processing from the last recovery checkpoint, requiring target tables to support idempotent or incremental loads
-
C
It automatically retries each failed row up to three times without restarting the session
-
D
It replaces the failed Secure Agent with a backup agent
