RabbitMQ - Performance Tuning

You wrote this code to batch publish messages but no messages appear in the queue:

channel.txSelect()
channel.basic_publish(exchange='', routing_key='queue', body='Hello')
channel.basic_publish(exchange='', routing_key='queue', body='World')

What is the likely problem?

AYou forgot to call channel.txCommit() to send the batch.

BYou must call channel.txRollback() after publishing.

CYou should use channel.basic_consume() instead of basic_publish().

DThe routing_key 'queue' is invalid and blocks messages.

Step-by-Step Solution

Solution:

Step 1: Check transaction usage
txSelect() starts transaction but no txCommit() means messages are not sent yet.
Step 2: Identify missing commit
Without txCommit(), messages stay uncommitted and invisible to consumers.
Final Answer:
You forgot to call channel.txCommit() to send the batch. -> Option A
Quick Check:
Missing txCommit() = no messages sent [OK]

Quick Trick: Always call txCommit() after batch publish [OK]

Common Mistakes:

MISTAKES

Calling txRollback() instead of txCommit()
Confusing consume with publish
Assuming routing_key 'queue' is invalid
