defmodule GoogleApi.Datastore.V1.Model.Aggregation do
  @moduledoc """
  Defines an aggregation that produces a single result.

  ## Attributes

  *   `alias` (*type:* `String.t`, *default:* `nil`) - Optional. Optional name of the property to store the result of the aggregation. If not provided, Datastore will pick a default name following the format `property_`. For example: ``` AGGREGATE COUNT_UP_TO(1) AS count_up_to_1, COUNT_UP_TO(2), COUNT_UP_TO(3) AS count_up_to_3, COUNT(*) OVER ( ... ); ``` becomes: ``` AGGREGATE COUNT_UP_TO(1) AS count_up_to_1, COUNT_UP_TO(2) AS property_1, COUNT_UP_TO(3) AS count_up_to_3, COUNT(*) AS property_2 OVER ( ... ); ``` Requires: * Must be unique across all aggregation aliases. * Conform to entity property name limitations.
  *   `avg` (*type:* `GoogleApi.Datastore.V1.Model.Avg.t`, *default:* `nil`) - Average aggregator.
  *   `count` (*type:* `GoogleApi.Datastore.V1.Model.Count.t`, *default:* `nil`) - Count aggregator.
  *   `sum` (*type:* `GoogleApi.Datastore.V1.Model.Sum.t`, *default:* `nil`) - Sum aggregator.
