AshClickhouse — an Ash Framework data layer for ClickHouse.

This library implements the Ash.DataLayer behaviour so that Ash resources can be backed by a ClickHouse columnar OLAP database. It uses the clickhouse client under the hood.

Quick start

defmodule MyApp.Repo do
  use AshClickhouse.Repo, otp_app: :my_app
end

defmodule MyApp.User do
  use Ash.Resource,
    data_layer: AshClickhouse.DataLayer,
    domain: MyApp.Domain

  clickhouse do
    table "users"
    repo MyApp.Repo
  end

  attributes do
    uuid_primary_key :id
    attribute :name, :string
    attribute :email, :string
  end

  actions do
    defaults [:create, :read, :update, :destroy]
  end
end

See AshClickhouse.DataLayer for the full list of supported features and AshClickhouse.Repo for connection configuration.
