Ecto integration for Apache Cassandra.

Documentation: http://hexdocs.pm/cassandra_ecto/

## Features

* Migrations (with UDT, UDF, UDA and materialized views support)

* Lightweight transactions

* Batching (only for `insert_all` queries)

* Streaming

## Example

```elixir

# 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.Schema

  @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

```

## Supported Cassandra version

Tested against 3.7+.

## Installation

  1. Add `cassandra_ecto` and `cqerl` to your list of dependencies in `mix.exs`:

    ```elixir

    def deps do

      [{:cqerl, github: "matehat/cqerl", tag: "v1.0.2", only: :test},

      {:cassandra_ecto, "~> 0.4.0"}]

    end

    ```

  2. Ensure `cassandra_ecto` and `cqerl` is started before your application:

    ```elixir

    def application do

      [applications: [:cassandra_ecto, :cqerl]]

    end

    ```

## Contributing

To contribute you need to compile `cassandra_ecto` from source and test it:

```

$ git clone https://github.com/vintikzzz/cassandra_ecto.git

$ cd cassandra_ecto

$ mix deps.get

$ mix espec

```
