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

clearUpTo()
public AggregationQuery.Aggregation.Count.Builder clearUpTo()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.

High-Level Example:
<code><code>
AGGREGATE COUNT_UP_TO(1000) OVER ( SELECT * FROM k );
</code></code>
Requires:
- Must be non-negative when present.
