Reference to the until() function



Returns synthetic events that start at the beginning of epoch time (Jan 1, 1970) and end where the input events start.


eventExpression Set of events that determine the ends of the returned synthetic events.


The until() event function returns a set of synthetic events, where each synthetic event:

  • Starts at the beginning of epoch time (Jan 1, 1970)
  • Ends at the start time of a corresponding event described by the expression.

The following diagram represents an events() query that returns 3 events (A, B, and C). Using that events() query as the input to until() produces 3 synthetic events that each end when the corresponding input event begins:

Note: Synthetic events are displayed by the query, but are not stored.
