Kafka - Multi-Datacenter and Replication
You want to ensure minimal data loss during a disaster. Which combination is best for Kafka disaster recovery?
AUse topic replication factor 3 and MirrorMaker to backup cluster
BUse only MirrorMaker without replication factor increase
CUse replication factor 1 and rely on manual backups
DUse Kafka Streams to replicate data to backup cluster
Step-by-Step Solution
Solution:

  1. Step 1: Understand replication factor role

    A replication factor of 3 means data is copied to 3 brokers, reducing data loss risk.

  2. Step 2: Combine with MirrorMaker backup

    MirrorMaker copies data to a separate cluster, adding disaster recovery protection.

  3. Final Answer:

    Use topic replication factor 3 and MirrorMaker to backup cluster -> Option A

  4. Quick Check:

    Replication + MirrorMaker = minimal data loss [OK]
Quick Trick: Combine replication factor and MirrorMaker for best safety [OK]
Common Mistakes:
MISTAKES
  • Relying only on MirrorMaker without replication
  • Using replication factor 1 which risks data loss
  • Confusing Kafka Streams with replication tool
