Which configuration enables exactly-once semantics in Kafka producer?
Aenable.idempotence=true
Backs=0
Cretries=0
Dcompression.type=none
Step-by-Step Solution
Solution:

  1. Step 1: Recall producer configs for exactly-once

    enable.idempotence=true enables idempotent producer, key for exactly-once.

  2. Step 2: Check other options

    acks=0 disables acknowledgments; retries=0 disables retries; compression unrelated.

  3. Final Answer:

    enable.idempotence=true -> Option A

  4. Quick Check:

    Idempotence enabled by enable.idempotence=true [OK]
Quick Trick: Set enable.idempotence=true for exactly-once producer [OK]
Common Mistakes:
MISTAKES
  • Confusing acks=0 with idempotence
  • Disabling retries breaks exactly-once
  • Ignoring idempotence setting
