The pipeline must ensure that all transactions are processed accurately and any exceptions are logged and handled appropriately. Describe how you would set up exception handling in this scenario, including the types of exceptions you would expect and the mechanisms you would use to manage them.
A
Use a try-catch block around the entire pipeline and log all exceptions to a centralized error log.
B
Implement specific exception handlers for common exceptions like data format errors and network failures, and use a dead-letter queue to manage unhandled exceptions.
C
Ignore exceptions and rely on the pipeline's built-in resilience mechanisms to handle any issues.
D
Periodically check the pipeline's health and manually intervene to resolve any exceptions.
