Kafka - Multi-Datacenter and Replication

Examine this MirrorMaker configuration snippet:
consumer.bootstrap.servers=source:9092 producer.bootstrap.servers=target:9092 topics=orders,payments whitelist=orders
What is the main issue with this configuration?

AThe producer.bootstrap.servers should point to the source cluster

BUsing both 'topics' and 'whitelist' properties simultaneously causes conflict

CThe consumer group ID is missing, causing consumer failures

DThe topics property should list only one topic at a time

Step-by-Step Solution

Solution:

Step 1: Understand MirrorMaker topic filtering
MirrorMaker uses either 'whitelist' or 'blacklist' to filter topics, not 'topics'.
Step 2: Identify conflict
Specifying both 'topics' and 'whitelist' leads to ambiguous topic selection.
Final Answer:
Using both 'topics' and 'whitelist' properties simultaneously causes conflict -> Option B
Quick Check:
Only one topic filter property should be used [OK]

Quick Trick: Use either whitelist or topics, not both [OK]

Common Mistakes:

Assuming producer.bootstrap.servers points to source
Forgetting to set consumer group ID
Thinking topics property accepts multiple topics without filtering
