Memmo

Memmo is a small library for creating key-based, in-memory caches in Ruby.

It features thread safety and TTLs.

Usage

require"memmo"
$memmo =Memmo.new
$memmo.register(:popular_posts,ttl: 60)do# Somewhat expensive queryPost.find(...)end# This call will trigger a miss and will run our expensive query.
$memmo[:popular_posts].eachdo |post|
puts(post)end# This call will be fast for the next 60 seconds.
$memmo[:popular_posts]

Test environments

It's common to avoid caches when testing your application. For this purpose you can disable Memmo entirely:

require"test/unit"Memmo.enabled=false
