Reference documentation and code samples for the Cloud Datastore V1 Client class Count.

Count of entities that match the query.

The COUNT(*) aggregation function operates on the entire entity so it does not require a field reference.

Generated from protobuf message google.datastore.v1.AggregationQuery.Aggregation.Count

Namespace

Google \ Cloud \ Datastore \ V1 \ AggregationQuery \ Aggregation

Methods

__construct

Constructor.

Parameters
Name	Description
data	array Optional. Data for populating the Message object.
↳ up_to	Google\Protobuf\Int64Value Optional. Optional constraint on the maximum number of entities to count. This provides a way to set an upper bound on the number of entities to scan, limiting latency, and cost. Unspecified is interpreted as no bound. If a zero value is provided, a count result of zero should always be expected. High-Level Example: AGGREGATE COUNT_UP_TO(1000) OVER ( SELECT * FROM k ); Requires: * Must be non-negative when present.

getUpTo
