If MirrorMaker 2 is set with 'emit.heartbeats.enabled' to false, what is the impact?
AReplication speed increases significantly
BTopics are automatically deleted after replication
CNo heartbeat messages are sent to monitor replication health
DSource cluster stops producing messages
Step-by-Step Solution
Solution:

  1. Step 1: Understand 'emit.heartbeats.enabled' role

    This setting controls whether heartbeat messages are sent to track replication status.

  2. Step 2: Analyze effects of disabling heartbeats

    Disabling heartbeats means no monitoring messages are sent; it does not affect speed, topic deletion, or source production.

  3. Final Answer:

    No heartbeat messages are sent to monitor replication health -> Option C

  4. Quick Check:

    emit.heartbeats.enabled false = no heartbeats sent [OK]
Quick Trick: Disable heartbeats with 'emit.heartbeats.enabled=false' [OK]
Common Mistakes:
MISTAKES
  • Assuming replication speed changes
  • Thinking topics get deleted automatically
  • Believing source cluster stops producing
