class HyperLogLogSeriesMonoid extends Monoid[HLLSeries]

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
