Kafka - with Java/Python

What will be the output of the following Python code using confluent-kafka producer?

from confluent_kafka import Producer

p = Producer({'bootstrap.servers': 'localhost:9092'})
p.produce('my_topic', key='key1', value='hello')
p.flush()
print('Message sent')

AError: No Kafka server found

Bhello

CNo output

DMessage sent

Step-by-Step Solution

Solution:

Step 1: Understand the code flow
The code creates a producer, sends a message to 'my_topic', waits for delivery with flush(), then prints 'Message sent'.
Step 2: Identify the printed output
The only print statement outputs the string 'Message sent'. The message sending is asynchronous but flush ensures completion before print.
Final Answer:
Message sent -> Option D
Quick Check:
flush() waits, then print runs [OK]

Quick Trick: flush() waits, print runs after sending [OK]

Common Mistakes:

MISTAKES

Expecting message value to print
Ignoring flush() effect
Assuming error without Kafka running
