  StorageService.instance().stopClient();

  A caveat of doing things this way is that a client cannot go up and down, and then up again without shutting down the entire VM.  I.e., you can't initClient(), stopClient() and then initClient() again.
- 
- == Ruby ==
- Install the Thrift gem that will take advantage of the native libraries (previously installed. Reference [[http://chrischandler.name/ruby/using-cassandras-thrift-interface-with-ruby/|Using Cassandra's Thrift Interface with Ruby]])
- 
- `shell> sudo gem install thrift`
- 
- Navigate to your Cassandra install’s interface directory (cassandra/interface) and build the ruby code:
- 
- `shell> thrift --gen rb:new_style cassandra.thrift`
- 
- {{{
- #!/usr/bin/env ruby require './cassandra' require './cassandra_constants' require './cassandra_types' require 'pp'
- 
- transport = Thrift::BufferedTransport.new(Thrift::Socket.new("localhost", "9160")) transport.open
- 
- client = CassandraThrift::Cassandra::Client.new(Thrift::BinaryProtocol.new(transport))
- 
- keyspace = "Keyspace1" key = "dude_login" columnPath = CassandraThrift::ColumnPath.new(:column_family => "Standard1", :column => "email") value = " dude@example.com " t = Time.now timestamp = t.to_i * 1_000_000 + t.usec
- 
- client.insert(keyspace, key ,columnPath, value, timestamp, CassandraThrift::ConsistencyLevel::ZERO)
- 
- begin
- 
-  . pp client.get(keyspace, key, columnPath, CassandraThrift::ConsistencyLevel::ONE)
- 
- rescue CassandraThrift::NotFoundException => e

-  . puts "Key not found."
