Acknowledgment modes (acks=0, 1, all) in Kafka - Mini Project: Build & Apply

Understanding Kafka Acknowledgment Modes (acks=0, 1, all)

📖 Scenario: You are working with Apache Kafka to send messages to a topic. Kafka allows you to control how it confirms message delivery using acknowledgment modes called acks. These modes help balance speed and reliability.In this project, you will create simple Kafka producer configurations to see how acks=0, acks=1, and acks=all work.

🎯 Goal: You will write Kafka producer configuration code snippets for each acknowledgment mode and print a message showing which mode is set. This will help you understand how to configure Kafka producers for different delivery guarantees.

📋 What You'll Learn

Create a Kafka producer configuration dictionary with acks set to 0

Create a variable called topic with the value 'test-topic'

Create a Kafka producer configuration dictionary with acks set to 1

Create a Kafka producer configuration dictionary with acks set to 'all'

Print the acks value from each configuration with a descriptive message

💡 Why This Matters

🌍 Real World

Kafka is widely used for building real-time data pipelines and streaming apps. Understanding acknowledgment modes helps ensure messages are delivered reliably or quickly depending on the need.

💼 Career

Kafka producer configuration is a key skill for backend developers, data engineers, and anyone working with event-driven systems or streaming data.

1

Create Kafka producer config with acks=0

Create a dictionary called producer_config_acks0 with the key 'acks' set to 0.

Kafka

# Create the producer_config_acks0 dictionary with 'acks' set to 0
# Your code here

Need a hint?

The acks key controls the acknowledgment mode. Setting it to 0 means no acknowledgment is required.

2

Create a topic variable

Create a variable called topic and set it to the string 'test-topic'.

Kafka

producer_config_acks0 = {'acks': 0}
# Create the topic variable with value 'test-topic'
# Your code here

Need a hint?

The topic variable holds the name of the Kafka topic where messages will be sent.

3

Create Kafka producer config with acks=1

Create a dictionary called producer_config_acks1 with the key 'acks' set to 1.

Kafka

producer_config_acks0 = {'acks': 0}
topic = 'test-topic'
# Create the producer_config_acks1 dictionary with 'acks' set to 1
# Your code here

Need a hint?

Setting acks to 1 means the leader broker will acknowledge the write.

4

Create Kafka producer config with acks='all' and print all configs

Create a dictionary called producer_config_acks_all with the key 'acks' set to the string 'all'. Then print the acks value from producer_config_acks0, producer_config_acks1, and producer_config_acks_all with messages exactly as shown below:
"acks=0 mode: 0"
"acks=1 mode: 1"
"acks=all mode: all"

Kafka

producer_config_acks0 = {'acks': 0}
topic = 'test-topic'
producer_config_acks1 = {'acks': 1}
# Create producer_config_acks_all with 'acks' set to 'all'
# Print the acks values from all three configs with the exact messages
# Your code here

Need a hint?

Use f-strings to print the acks values with the exact messages.
