RabbitMQ - Performance Tuning

Which of the following is the correct way to set prefetch_count to 10 using RabbitMQ's basic.qos command?

A<code>channel.set_qos(10)</code>

B<code>channel.prefetch(10)</code>

C<code>channel.basic_qos(prefetch_count=10)</code>

D<code>channel.qos(prefetch=10)</code>

Step-by-Step Solution

Solution:

Step 1: Recall RabbitMQ client method for QoS
The correct method to set prefetch count is basic_qos with prefetch_count argument.
Step 2: Match syntax with options
channel.basic_qos(prefetch_count=10) uses channel.basic_qos(prefetch_count=10), which is the correct syntax.
Final Answer:
channel.basic_qos(prefetch_count=10) -> Option C
Quick Check:
basic_qos with prefetch_count sets limit = B [OK]

Quick Trick: Use basic_qos(prefetch_count=number) to set prefetch [OK]
