This is basically just a thin JRuby extension wrapping the spymemcached client.

Building

I used Maven because I'm lazy.

mvn package
gem build src/main/ruby/jruby-spymemcached.gemspec

Usage

require 'rubygems'
require 'jruby-memcached'

memcached = Spymemcached.new(['localhost:11211'])

memcached.set('foo', 'bar') # synchronous set
future = memcached.async_set('foo', 'bar') # async set
#...
future.get # or not, if you don't care about result

memcached.get('foo')
10.times {
  Thread.new {
    25_000.times { memcached.get('foo') } # concurrency-friendly
  }
}
memcached.multiget(['foo', 'foo', 'foo', 'foo']) # get multi

future = memcached.async_get('foo') # async get, returns a future
#...
future.get

future = memcached.async_multiget(['foo', 'foo', 'foo', 'foo']) # ditto
#...
future.get

memcached.shutdown if JRUBY

TODO

• API-compatible wrappers for the popular Ruby memcached libs.
• More spymemcached feature exposure
