Methods

#up_to

def up_to() -> ::Google::Protobuf::Int64Value
Returns
  • (::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.
