Kafka - Performance Tuning

You tried to create a Kafka topic with 0 partitions using the command: kafka-topics --create --topic test --num-partitions 0 --bootstrap-server localhost:9092. What is the likely issue?

AKafka allows 0 partitions, so topic created with no data storage

BError because partition count must be at least 1

CTopic created with default partition count of 1

DCommand ignored the partition count and created topic anyway

Step-by-Step Solution

Solution:

Step 1: Understand partition count constraints
Kafka requires at least one partition per topic; zero is invalid.
Step 2: Identify command behavior
Setting partitions to 0 causes an error because Kafka cannot create a topic without partitions.
Final Answer:
Error because partition count must be at least 1 -> Option B
Quick Check:
Partition count ≥ 1 required [OK]

Quick Trick: Partition count cannot be zero or negative [OK]

Common Mistakes:

Assuming Kafka defaults to 1 partition silently
Thinking zero partitions means no data but topic exists
Ignoring error messages from Kafka CLI
