Allowing to attach callbacks in kafka streams, to be triggered when a window is expired, would help in use cases when the final state of the window is required. It would be also useful if together with that functionally the user would be able to control whether the callback would be triggered in addition to emitting the normal change log down the stream, or only triggering the callback when the window is expired. (for example in cases when only the final window state is required, and any updates to the window state during the window time interval are not important) -- This message was sent by Atlassian JIRA (v7.6.3#76005)
