DownsampledInstantaneousMetricData

class DownsampledInstantaneousMetricData : MetricData

Downsamples instantaneous metric data using reservoir sampling.

For instantaneous metrics, this implementation maintains approximately DESIRED_SAMPLES samples using Algorithm R (standard reservoir sampling). While this is visually lossy, scatter plots are primarily used to identify general patterns. Every sample has an equal probability of being preserved, providing uniform and unbiased sampling across the entire time series.

Types

Sample

data class Sample(val sequenceId: Long, val time: Instant, val value: Double) : Comparable<DownsampledInstantaneousMetricData.Sample>

A single metric sample at a specific point in time.

Properties

values

open override val values: PersistentList<MetricValue>

All metric values stored in this data object, in chronological order.

Functions

add

open override fun add(currentTime: Instant, value: Double)

Adds a new metric value using reservoir sampling (Algorithm R).
