Improve performance of bundle events processing in async listener
-----------------------------------------------------------------
Key: NXP-5995
URL: https://jira.nuxeo.org/browse/NXP-5995
Project: Nuxeo Enterprise Platform
Issue Type: Improvement
Affects Versions: 5.4
Reporter: Benoit Delbosc
Async listener should not iterate on events when receiving EventBunde
public void handleEvent(EventBundle events) {
for (Event event : events) {
handleEvent(event);
}
}
For async listener events are ReconnectedEventBundle and iterating on them will
reconnect all events, this means opening a session and create document model
and context for each event (see
ReconnectedEventBundleImpl.getReconnectedEvents())
This is very expensive and useless if the listener is not interested in any
event in the bundle.
A first optimisation may be to use containsEventName in the listener to check
if the interesting event is present in the bundle,
that should not reconnect any events.
