delta_sum

Sums only positive step-to-step increases in a numeric sequence, ignoring negative jumps that typically represent counter resets.

Kind · aggregate

Sums only positive step-to-step increases in a numeric sequence, ignoring negative jumps that typically represent counter resets.

Part of the Time Series family.

delta_rate

Computes per-event delta-per-second against the previous event using either explicit timestamp/value columns or sequence-based fallback when only a value column is present.

delta_sum_timestamp

Computes positive delta accumulation for timestamped counter values. In this V1 implementation, values are consumed in input order.
