-------------------------------------
Summary: [PERF] Moving a bunch of emails trigger notif storm
Key: JAMES-4188
URL: https://issues.apache.org/jira/browse/JAMES-4188
Project: James Server
Issue Type: Improvement
Components: JMAP
Reporter: Benoit Tellier
Assignee: Antoine Duprat
h3. Why ?
GIVEN bob moves 25 emails
WHEN he observes messages in JMAP websocket
THEN he sees 25 state changes
Failure to group messages results in excessive usage of the EventBus causing
undue pressure of the RabbitMQ component, and over-uses James COUs.
h3. Root cause
Apparently this is due to the uid being non contiguous: it result in several
distinct range updates and not just one that would bundle the events together..
