Reference documentation and code samples for the Google Cloud Datastore v1 API class AggregationResult.
The result of a single bucket from a Datastore aggregation query.
The keys of aggregate_properties are the same for all results in an
aggregation query, unlike entity queries which can have different fields
present for each result.
The result of the aggregation functions, ex: COUNT(*) AS total_entities.
The key is the
[alias][google.datastore.v1.AggregationQuery.Aggregation.alias] assigned to
the aggregation function on input and the size of this map equals the
number of aggregation functions in the query.
