memcache-client¶ ↑

A ruby library for accessing memcached.

memcache-client is deprecated as of August 2010. It will be supported through 2010 but new code should use Dalli instead.¶ ↑

Installing memcache-client¶ ↑

Just install the gem:

$ sudo gem install memcache-client

Using memcache-client¶ ↑

With one server:

CACHE = MemCache.new 'localhost:11211'

Or with multiple servers:

CACHE = MemCache.new %w[one.example.com:11211 two.example.com:11211]

Tuning memcache-client¶ ↑

The MemCache.new method takes a number of options which can be useful at times. Please read the source comments there for an overview. If you are using Ruby 1.8.x and using multiple memcached servers, you should install the RubyInline gem for ultimate performance.

Using memcache-client with Rails¶ ↑

Rails 2.1+ includes memcache-client 1.5.0 out of the box. See ActiveSupport::Cache::MemCacheStore and the Rails.cache method for more details. Rails 2.3+ will use the latest memcache-client gem installed.

Using memcache-client with EventMachine¶ ↑

memcache-client 1.8.0 added support for native EventMachine connections using Ruby 1.9. If you are using an EventMachine-based application (e.g. thin), you can activate the EventMachine support like so:

require 'memcache'
require 'memcache/event_machine'

EM.run do
  Fiber.new do
    m = MemCache.new('localhost:11211')
    m.set 'abc', 'xyz'
    m.get 'abc'
  end.resume
end
