Step-by-Step Solution
Solution:
Step 1: Understand partition increase effect
Increasing partitions without adding brokers means more load per broker.Step 2: Analyze cluster behavior
Kafka does not auto-add brokers; load per broker rises, risking performance issues.Final Answer:
The load per broker increases, possibly causing performance issues -> Option CQuick Check:
More partitions + same brokers = more load per broker [OK]
Quick Trick: More partitions without brokers = more load per broker [OK]
Common Mistakes:
- Assuming Kafka auto-adds brokers
- Thinking consumers must be reduced
- Believing Kafka rejects partition increase
