The win_session node


Since 0.17.2

This window refers it's timing to the timestamp contained in the incoming data-items.

A session window aggregates records into a session, which represents a period of activity separated by a specified gap of inactivity. Any data_points with timestamps that occur within the inactivity gap of existing sessions will be added to this session. If a data_point's timestamp occurs outside the session gap, a new session is created. A new session window starts if the last record that arrived is further back in time than the specified inactivity gap.





Every data_point, that has a timestamp < last-timestamp + session_timeout, will be member of the current window.


Parameter Description Default
