Redis - Delete Multiple Keys by Pattern Using Lua Script

This guide provides a simple Lua script to delete multiple keys in Redis that match a specific pattern.

Usage

Run the script from within the Redis CLI.
Replace PATTERN in the script below with the actual key substring you want to delete in bulk.

eval "for _,k in ipairs(redis.call('keys','*PATTERN*')) do redis.call('del',k) end" 0

Explanation

The eval command executes the Lua script.
redis.call('keys','*PATTERN*') retrieves all keys matching the specified pattern.
The for loop iterates through the list of keys and deletes each one using redis.call('del',k).
The 0 at the end indicates that no additional arguments are passed to the script.
