Returns an instance of
T calculated by summing all instances in iter in one pass. Returns None if
iter is empty, else Some[
T].
instances of
T to be combined
None if iter is empty, else an option value containing the summed
T
Example Usage
val hllSeriesMonoid = new HyperLogLogSeriesMonoid(bits)
val examples: Seq[Array[Byte], Long] val series = examples .map { case (bytes, timestamp) => hllSeriesMonoid.create(bytes, timestamp) } .reduce { hllSeriesMonoid.plus(_,_) }
val estimate1 = series.since(timestamp1.toLong).toHLL.estimatedSize val estimate2 = series.since(timestamp2.toLong).toHLL.estimatedSize
