To respect the semantic of "update" properly, we need "retraction" to provide two different events, remove old session and insert updated session. This could be implemented manually with flatMapGroupsWithState, though I'm not sure this is performant enough in practice, since it requires two operations "delete" and "insert" against external storage. -- This is an automated message from the Apache Git Service.
