1. How do I set and get a key in this Redis compiler?

Use SET to store a value and GET to retrieve it.

You can also store a simple message:

For a numeric counter:

Enter the commands in the Code Editor, click Run, and review the returned values in the Output screen.

2. Do I need to install Redis Server or redis-cli locally?

No. You can use this Online Redis Compiler / CLI directly from your browser for supported Redis exercises without installing Redis Server or redis-cli.

A local or hosted Redis environment may still be needed for production applications, persistent datasets, authentication, clustering, replication, external application connections, and advanced server configuration.

3. Can I test Redis data structures like Hashes and Lists here?

Yes. You can practice supported Redis data structures such as Hashes and Lists.

A Redis Hash example:

A Redis List example:

You can also experiment with sets:

These commands are useful for understanding how Redis stores structured data beyond simple string values.

4. Is Redis a NoSQL database?

Yes. Redis is commonly classified as a NoSQL key-value data store and is designed for very fast in-memory data access. It supports multiple data structures rather than traditional relational tables and SQL queries.

For example, a simple Redis caching workflow can look like this:

Redis is widely used for caching, sessions, counters, queues, rate limiting, real-time application data, and other workloads where fast access is important.
