Class AggregationQuery.Aggregation.Count (2.20.2)

public static final class AggregationQuery.Aggregation.Count extends GeneratedMessageV3 implements AggregationQuery.Aggregation.CountOrBuilder

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];

Returns
Type Description
Int64Value

The upTo.
