Why is it important to handle retriable exceptions differently from non-retriable exceptions in Kafka clients?
ANon-retriable exceptions can be retried safely without side effects
BBoth exception types should be ignored to improve performance
CRetriable exceptions indicate temporary issues; non-retriable indicate permanent failures
DRetriable exceptions cause the client to shut down immediately
Step-by-Step Solution
Solution:
  1. Step 1: Understand exception types

    Retriable exceptions mean temporary problems like network glitches; non-retriable mean permanent errors like invalid data.
  2. Step 2: Importance of different handling

    Retriable exceptions should trigger retries; non-retriable should cause error handling without retry to avoid infinite loops.
  3. Final Answer:

    Retriable exceptions indicate temporary issues; non-retriable indicate permanent failures -> Option C
  4. Quick Check:

    Retriable vs non-retriable = temporary vs permanent [OK]
Quick Trick: Retry only on temporary (retriable) exceptions [OK]
