Benoit Tellier commented on JAMES-3559:
---------------------------------------
Hello [~rouazana]
How do you connect the two events systems? You would need to record IMAP and
SMTP changes to be consumed by JMAP.
IMAP events could still result in several mailbox events that would lead to
several notifications.
By the way, this is a major rework, that is not doable given my deployments
timeline. Hence I would really appreciate having a reasonable short term
mitigation mechanism.
> JMAP PUSH: window events on the server side?
> --------------------------------------------
>
> Key: JAMES-3559
> URL: https://issues.apache.org/jira/browse/JAMES-3559
> Project: James Server
> Issue Type: Improvement
> Components: JMAP
> Affects Versions: 3.6.0
> Reporter: Benoit Tellier
> Assignee: Antoine Duprat
> Priority: Major
> Time Spent: 0.5h
> Remaining Estimate: 0h
>
> h3. Why?
> Today a JAMES action might trigger several events being dispatched on the
> event bus (eg moving 2 messages will end up firing 2 additions and 2
> deletion) resulting in likely 4 StateChanges being pushed to the end user.
> h3. How?
> Using the reactor library, James can likely delay pushes for a given
> timewindow and merge the state changes together in order to supply the client
> with only one state change.
> A likely time value might be 2 seconds.
> - Pros: avoid event storm and will lower re-synchronization request count
> (good for perf?)
> - Cons: delays of 2s for real time across devices.
> We could of course make it configurable via a jmap.properties configuration.
> {code:java}
> # Optional. Omiting this property leads to windowing being disables. James
> will
> # then directly forward all StateChanges to the end user without attempting
> to
> # buffer and aggregating them.
> # If specified, James will delay stateChanges for that given amout of time
> and will attempt
> # to aggregate subsequent state changes together before returning them to the
> client.
> # Units: ms, s, min, h, d
> push.aggregation.window.duration=2s
> {code}
> Thoughts [~inputmice] maybe?
