CassandraORM

A simple Cassandra ORM library, which can provide with a CRUD model to operate Cassandra. Based on cassandra-driver.

Or install it yourself as:

$ gem install cassandra-orm

require 'cassandra-orm'
require 'logger'

CassandraORM.configure keyspace: 'test', logger: Logger.new(STDERR)
CassandraORM.connect

class User < CassandraORM::Model
  set_primary_key :email
  attributes :name, :age
end

user = User.new email: 'bachue.shu@gmail.com', name: 'Bachue Zhou', age: 25
user.save exclusive: true # save it only when there's no user whose email is 'bachue.shu@gmail.com'

user.age = 26
user.save if: {age: 25} # update it only when his age is still 25

user.destroy # returns true, delete the record
