Instance Attribute Details

#up_to ⇒ Fixnum

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. Corresponds to the JSON property upTo

Returns:

• (Fixnum)
