Class AggregationResult (2.18.5)

public final class AggregationResult extends GeneratedMessageV3 implements AggregationResultOrBuilder

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.

Protobuf type google.datastore.v1.AggregationResult
