Redis is a fast, open-source, in-memory key-value data store used for a variety of applications. One of the powerful features of Redis is its ability to handle batch operations efficiently using pipelines.

When using pipelines, the Redis client groups multiple commands together and sends them as a single request to the Redis server. The server processes these commands sequentially and sends the responses back in a single batch. This eliminates the round-trip time for each individual command, significantly reducing latency for batch operations.

By bundling multiple commands, pipelines reduce the interaction time between the client and server, optimizing performance for larger data operations.

The following section demonstrates how to utilize Redis pipelines effectively using the Lettuce library. We'll learn how to create and execute batch commands.
