Redis Scripts

Elegant redis scripting for ruby.

Show me

require 'redis_scripts'

# Grab a redis handle.
redis = Redis.new

# Configure the scripts location. Can also be done globally via
# RedisScripts.load_path.
redis.scripts.load_path = '/path/to/scripts'

# Run the script at /path/to/scripts/foo.lua .
redis.scripts.run :foo, keys, values

The call to run intuitively translates to a call to EVALSHA. If the SHA is not in the redis script cache, it will be loaded (with SCRIPT LOAD), and then re-executed via EVALSHA, ensuring future calls are optimal.

Priming the cache

You can load all scripts into cache ahead of time like this:

redis.scripts.load_all

You could do this, for example, each time you deploy updates to your application.

Emptying the cache

Redis does not offer a way to list or delete individual scripts. To clear out the script cache, you'll need to call redis.script 'flush' to empty the cache entirely. You can then call load_all to reload your scripts, or just let subsequent calls to run restore them as needed.
