Lua scripting

With Redis, developers can write Lua scripts and execute them within Redis. Lua is a lightweight scripting language known for its simplicity and efficiency, and Redis has leveraged its power to perform complex operations on stored data since Redis 2.6.0. Lua scripting offers several benefits, such as allowing the execution of multiple commands atomically, meaning all the commands within a Lua script will be executed as a single unit of work, ensuring consistency. This is particularly useful to ensure they are executed without interruption or interference from other clients.

By executing Lua scripts, the network round trips between the application and the server are removed, improving performance. Lua scripts are sent to Redis as an atomic block of instructions and executed directly on the server, eliminating the need to send multiple commands and receive responses individually.

Redis provides a Lua interpreter with a set of Redis-specific Lua functions that allow...
