Kafka - Producers

Consider this code snippet for sending messages without keys:

for i in range(4):
    producer.send("topic", value=f"msg{i}")

What is the likely issue if all messages end up in the same partition?

AMessages have keys that force same partition

BTopic has only one partition

CThe producer is not configured to use round-robin partitioning

DProducer is using a custom partitioner ignoring keys

Step-by-Step Solution

Solution:

Step 1: Analyze message keys and partition count
Messages have no keys, so default partitioner uses round-robin if multiple partitions exist.
Step 2: Check topic partition count
If all messages go to the same partition, likely the topic has only one partition.
Final Answer:
Topic has only one partition -> Option B
Quick Check:
Single partition topic = all messages same partition [OK]

Quick Trick: Single partition topic sends all messages there [OK]
