public static final class AggregationQuery . Aggregation . Count extends GeneratedMessageV3 implements AggregationQuery . Aggregation . CountOrBuilder
Count of entities that match the query.
The COUNT(*) aggregation function operates on the entire entity
so it does not require a field reference.

getUpTo()
public Int64Value getUpTo ()
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:
<code><code>
AGGREGATE COUNT_UP_TO(1000) OVER ( SELECT * FROM k );
</code></code>
Requires:
Must be non-negative when present.
.google.protobuf.Int64Value up_to = 1 [(.google.api.field_behavior) = OPTIONAL];
