Joerg Hoh updated SLING-10968:
------------------------------
Summary: Reduce reload events on content changes (was: Reduce aliasreload
events on content changes)
> Reduce reload events on content changes
> ---------------------------------------
>
> Key: SLING-10968
> URL: https://issues.apache.org/jira/browse/SLING-10968
> Project: Sling
> Issue Type: Improvement
> Components: ResourceResolver
> Affects Versions: Resource Resolver 1.8.0
> Reporter: Joerg Hoh
> Priority: Major
>
> Currently whenever a relevant change to the vanity paths is detected, a
> respective event is sent [1]. This event does not contain the location of the
> actual change, but only the fact that such an event happened [2].
> If multiple of such events happen within the list of changes processed by a
> single invocation of the {{onChange()}} method, multiple events are sent.
> This can be optimized in a way, that if it has been determined, that a change
> event must ben sent, the remaining (not yet-processed) events can be ignored,
> because an event will be sent anyway.
> Now instead of potential multiple events just a single event is fired (if at
> all).
