Welcome to the Redis tutorial! Redis is an open-source, in-memory data structure store, used as a database, cache, and message broker. It supports various data structures such as strings, hashes, lists, sets, and sorted sets.

Basic Concepts

  • Data Structures: Redis supports various data structures, which make it versatile for different use cases.
  • In-Memory: Unlike traditional databases, Redis stores data in memory, which allows for fast read and write operations.
  • Persistence: Redis can be configured to persist data to disk, ensuring data is not lost in case of a system crash.

Installation

To install Redis on your system, you can visit the official Redis website and follow the instructions for your specific operating system.
