OptionaldelayOptionaloffsetNon-negative phase shift from the default midnight UTC alignment. For example, offset=22h on a 24h slide produces boundaries at 22:00 UTC (17:00 New York in standard time) instead of midnight UTC. If unset, the offset is zero. Must be shorter than slide_duration (and therefore window_duration).
OptionalslideThe slide duration (interval by which windows advance, must be positive and less than duration).
OptionalwindowThe duration of the sliding window. Must be positive when set; absent means lifetime (aggregate over the entity's entire history).
Non-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.
