Ecto integration for Apache Cassandra.

Cassandra adapter implements 3 behaviours:

• Ecto.Adapter
• Ecto.Adapter.Storage
• Ecto.Adapter.Migration

Every behaviour implementation stays in separate file with appropriate docs. Please view for more information:

• Cassandra.Ecto.Adapter
• Cassandra.Ecto.Storage
• Cassandra.Ecto.Migration

Usage example

# In your config/config.exs file
config :my_app, Repo,
  keyspace: "my_keyspace"

# In your application code
defmodule Repo do
  use Ecto.Repo,
    otp_app: :my_app,
    adapter: Cassandra.Ecto
end

defmodule Post do
  use Ecto.Model

  @primary_key {:id, :binary_id, autogenerate: true}
  schema "posts" do
    field :title,    :string
    field :text,     :string
    field :tags,     {:array, :string}
    timestamps()
  end
end

defmodule Simple do
  import Ecto.Query

  def sample_query do
    query = from p in Post, where: "elixir" in p.tags
    Repo.all(query, allow_filtering: true)
  end
end
