Batch publishing for throughput in RabbitMQ - Mini Project: Build & Apply

Batch publishing for throughput

📖 Scenario: You are working on a messaging system using RabbitMQ. To improve performance, you want to send messages in batches instead of one by one. This helps reduce network overhead and increases throughput.

🎯 Goal: Build a simple RabbitMQ publisher script that sends messages in batches of a fixed size to a queue.

📋 What You'll Learn

Create a list of 10 messages with exact content

Set a batch size variable to 3

Use a loop to publish messages in batches of 3

Print the total number of messages published

💡 Why This Matters

🌍 Real World

Batch publishing is used in messaging systems to improve speed and reduce network load by sending multiple messages together.

💼 Career

Understanding batch publishing helps in roles like DevOps engineer or backend developer working with message brokers such as RabbitMQ.

1

Create the message list

Create a list called messages with these exact string entries: 'msg1', 'msg2', 'msg3', 'msg4', 'msg5', 'msg6', 'msg7', 'msg8', 'msg9', 'msg10'.

RabbitMQ

# Create the list of messages
# Your code here

Need a hint?

Use square brackets to create a list and separate each message with commas.

2

Set the batch size

Create a variable called batch_size and set it to the integer 3.

RabbitMQ

messages = ['msg1', 'msg2', 'msg3', 'msg4', 'msg5', 'msg6', 'msg7', 'msg8', 'msg9', 'msg10']
# Set batch_size to 3
# Your code here

Need a hint?

Just assign the number 3 to the variable batch_size.

3

Publish messages in batches

Use a for loop with variable i to iterate over range(0, len(messages), batch_size). Inside the loop, create a batch slice called batch from messages[i:i+batch_size]. Then simulate publishing by printing Publishing batch: {batch}.

RabbitMQ

messages = ['msg1', 'msg2', 'msg3', 'msg4', 'msg5', 'msg6', 'msg7', 'msg8', 'msg9', 'msg10']
batch_size = 3
# Loop over messages in steps of batch_size and print each batch
# Your code here

Need a hint?

Use slicing to get each batch and print it inside the loop.

4

Print total messages published

After the loop, write a print statement to display the exact text: Total messages published: 10.

RabbitMQ

messages = ['msg1', 'msg2', 'msg3', 'msg4', 'msg5', 'msg6', 'msg7', 'msg8', 'msg9', 'msg10']
batch_size = 3
for i in range(0, len(messages), batch_size):
    batch = messages[i:i+batch_size]
    print(f"Publishing batch: {batch}")
# Print total messages published
# Your code here

Need a hint?

Use a print statement exactly as shown to show the total count.
