voldemort-rb
Installing the Gem from rubygems
sudo gem install voldemort-rb
Requirements
Since the communication between the client and the server is done using protocol buffers you'll need the ruby_protobuf gem found at http://code.google.com/p/ruby-protobuf/.
sudo gem install ruby_protobuf
XML Parsing is done using Nokogiri
sudo gem install nokogiri
Building and Installing the Gem from source
gem build voldemort-rb.gemspec
sudo gem install voldemort-rb-0.1.X.gem (replace 'X' with the correct version)
Examples
Basic Usage
Connecting and bootstrapping
client = VoldemortClient.new("test", "localhost:6666")
Storing a value
client.put("some key", "some value")
Reading a value
client.get("some key")
you'll get
=> some value
deleting a value from a key
client.delete("some key")
Conflict resolution
Default
Voldemort replies with versions of a value, it's up to the client to resolve the conflicts. By default the library will return the version that's most recent.
Custom
You can override the default behavior and perform a custom resolution of the conflict, here's how to do so:
client = VoldemortClient.new("test", "localhost:6666") do |versions|
versions.first # just return the first version for example
end
