OptionaldelayNon-negative analytic lag that evaluates the window this far in the past. Use this for timing variations unrelated to source lateness, such as a 30-day count as of one week ago. If unset, the analytic lag is zero. It composes with source.lateness when both are set.
OptionalwindowThe duration of the rolling window. Must be positive when set; absent means lifetime (aggregate over the entity's entire history).
A rolling time window with an optional non-negative delay.
