MemCachier Rails Elastic Beanstalk Tutorial App

This is an example Rails application that demonstrates the use of caching using MemCachier on AWS Elastic Beanstalk. This example is written with Rails 5.2.

You can read the full tutorial here.

Setup MemCachier

Setting up MemCachier to work in Rails is very easy. You need to make changes to Gemfile, production.rb, and any app code that you want cached. These changes are covered in detail below.

Gemfile

MemCachier has been tested with the dalli memcache client. Add the following gem to your Gemfile:

gem 'dalli'

production.rb

Ensure that the following configuration option is set in production.rb:

config.cache_store = :mem_cache_store,
                    (ENV["MEMCACHIER_SERVERS"] || "").split(","),
                    {:username => ENV["MEMCACHIER_USERNAME"],
                     :password => ENV["MEMCACHIER_PASSWORD"],
                     :failover => true,
                     :socket_timeout => 1.5,
                     :socket_failure_delay => 0.2,
                     :down_retry_delay => 60
                    }

Using MemCachier

In your application, use Rails.cache methods to access MemCachier. A list of methods is available here. All the built-in Rails caching tools will work, too.
