Reference documentation and code samples for the Firestore in Datastore mode V1 API class Google::Cloud::Datastore::V1::AggregationQuery::Aggregation::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.

Methods
#up_to
def up_to() -> ::Google::Protobuf::Int64Value-
(::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.
