Kafka - with Java/Python

Identify the error in this Python confluent-kafka producer code:

from confluent_kafka import Producer

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

AMissing key argument in produce()

BIncorrect order of arguments in produce()

Cflush() called before produce()

DMissing import statement

Step-by-Step Solution

Solution:

Step 1: Check produce() argument order
The produce() method expects positional arguments first (topic, optionally value), followed only by keyword arguments. Here, key='key1' (keyword) is followed by 'hello' (positional), causing SyntaxError: positional argument follows keyword argument.
Step 2: Identify correct usage
Correct usage: produce('my_topic', value='hello') or produce('my_topic', key='key1', value='hello').
Final Answer:
Incorrect order of arguments in produce() -> Option B
Quick Check:
Positional args before keywords [OK]

Quick Trick: Positional args must precede keywords [OK]
