Cassandra Record

Installation

Add this line to your application's Gemfile:

gem 'cassandra_record'

And then execute:

$ bundle

Or install it yourself as:

$ gem install cassandra_record

Usage

CassandraRecord models are based on the following Cassandra table:

CREATE TABLE thingies (
  id int,
  name text,
  PRIMARY KEY (id)
);

A simple Cassandra-backed model

Define the model by inheriting from CassandraRecord::Base. ...and you're done. ...you're welcome

class Thingy < CassandraRecord::Base
end

# record creation
Thingy.create(id: 123, name: 'pizza')

# record retrieval and attribute access
my_thingy = Thingy.where(id: 123)
my_thingy.name   # => pizza

A model with creation options

Override the instance-level #create method. Overriding the instance-level #create method will apply the configured options to all created records.

class Thingy < CassandraRecord::Base
  TTL = 3600 # one hour

  def create
    options = { ttl: TTL }
    super(options)
  end
end

# record creation
# this record will auto-expire in 1 hour.
Thingy.create(id: 123, name: 'spaghetti')
