What is the effect of setting cluster_partition_handling to 'autoheal' in a RabbitMQ cluster after a network partition?
AThe cluster ignores the partition and continues independently
BThe cluster automatically resolves the partition and merges data
CThe cluster deletes all queues on minority nodes
DThe cluster shuts down all nodes until manual intervention
Step-by-Step Solution
Solution:
  1. Step 1: Understand 'autoheal' behavior

    This setting enables automatic resolution and data merging after partitions.
  2. Step 2: Identify the effect on the cluster

    The cluster heals itself by merging queues and resuming normal operation.
  3. Final Answer:

    The cluster automatically resolves the partition and merges data -> Option B
  4. Quick Check:

    autoheal = automatic partition resolution [OK]
Quick Trick: autoheal merges data and heals partitions automatically [OK]
Common Mistakes:
MISTAKES
  • Assuming autoheal ignores partitions
  • Thinking it deletes queues automatically
  • Believing it requires manual restart
