> I came across a requirement to support session-based windowing. for example, user activity comes in from kafka, we want to create window per user session (if the time gap of activity from the same user exceeds the predefined value, a new window will be created).
> I noticed that Flink does support this kind of support, any plan/schedule for spark for this?
