SET and GET commands in Redis - Mini Project: Build & Apply

Using Redis SET and GET Commands

📖 Scenario: You are managing a simple user session store in Redis. Each user has a unique session ID, and you want to save and retrieve session data quickly.

🎯 Goal: Learn how to use Redis SET to store session data and GET to retrieve it.

📋 What You'll Learn

Use the SET command to store a session ID with its data

Use the GET command to retrieve the session data by session ID

Use exact session IDs and data values as specified

💡 Why This Matters

🌍 Real World

Storing and retrieving user session data quickly in a web application.

💼 Career

Understanding SET and GET commands is essential for working with Redis in backend development and caching.

1

Create a session key with SET

Use the Redis SET command to create a key called session:12345 with the value user_data_abc.

Redis

# Use SET to create the session key
# Your code here

Need a hint?

The SET command syntax is: SET key value.

2

Create another session key with SET

Use the Redis SET command to create a key called session:67890 with the value user_data_xyz.

Redis

SET session:12345 user_data_abc
# Use SET to create another session key
# Your code here

Need a hint?

Remember to use the exact key and value given.

3

Retrieve a session value with GET

Use the Redis GET command to retrieve the value stored at the key session:12345.

Redis

SET session:12345 user_data_abc
SET session:67890 user_data_xyz
# Use GET to retrieve the first session value
# Your code here

Need a hint?

The GET command syntax is: GET key.

4

Retrieve the second session value with GET

Use the Redis GET command to retrieve the value stored at the key session:67890.

Redis

SET session:12345 user_data_abc
SET session:67890 user_data_xyz
GET session:12345
# Use GET to retrieve the second session value
# Your code here

Need a hint?

Retrieve the second session value using the exact key.
