Kafka - Multi-Datacenter and Replication

ASet up MirrorMaker 2 with a full mesh replication where each cluster replicates to the other two

BUse a single MirrorMaker 2 instance replicating only from US to EU and Asia

CConfigure MirrorMaker 2 to replicate only the largest topic across clusters

DUse Kafka Connect Sink to move data between clusters

Step-by-Step Solution

Solution:

Step 1: Understand full data availability goal
Each cluster should have all topics from the others, meaning data must flow both ways between all clusters.
Step 2: Choose replication strategy
A full mesh replication with MirrorMaker 2 means each cluster replicates to the other two, ensuring complete data presence everywhere.
Final Answer:
Set up MirrorMaker 2 with a full mesh replication where each cluster replicates to the other two -> Option A
Quick Check:
Full mesh replication = all clusters have all topics [OK]

Quick Trick: Full mesh replicates all topics between all clusters [OK]

Common Mistakes:

Using one-way replication only
Replicating only largest topic, missing others
Confusing Kafka Connect Sink with cluster replication
