I have been recently picking up more learnings with Memcached and how Dalli plays along with the different caching strategies. I am trying to connect remotely to our memcachier on heroku with one of our production level projects. Through some tutorial, I found out how to connect remotely to remote memcachier through Dalli.
sandbox.rb:
require 'dalli'
memcachier_server = 'host_name:port'
memcachier_user = 'abc123'
memcachier_password = '1x8w3asdf82jdf'
cache = Dalli::Client.new(memcachier_server,
{
:username => memcachier_user,
:password => memcachier_password,
:failover => true,
:socket_timeout => 1.5,
:socket_failure_delay => 0.2
})
p cache.stat
I confirmed it works when i run ruby sandbox.rb and there comes the output:
I, [2015-03-17T01:45:20.703729 #42640] INFO -- : Dalli/SASL authenticating as abc123
I, [2015-03-17T01:45:21.305454 #42640] INFO -- : Dalli/SASL: abc123

I have been trying to find out how I can dig in more into the cached keys and values. To be more specific: I want to at least list out all Keys and values currently in memcached using Dalli. I can't seem to find an appropriate solution. The best match i found is this gist which helps you with getting it locally.
Any thoughts?
