Carsten Ziegeler commented on SLING-9040:
-----------------------------------------
[~sonagupt], [~rombert], [~diru] Reading the last comment, it seems there are
issues with this change - if so we need to reopen and fix to unblock potential
resource resolver releases
> High resource consumption when activating/deactivating ResourceProviders
> ------------------------------------------------------------------------
>
> Key: SLING-9040
> URL: https://issues.apache.org/jira/browse/SLING-9040
> Project: Sling
> Issue Type: Bug
> Components: ResourceResolver
> Reporter: Dirk Rudolph
> Assignee: Robert Munteanu
> Priority: Blocker
> Fix For: Resource Resolver 1.6.18
>
> Time Spent: 40m
> Remaining Estimate: 0h
>
> With SLING-8946 the updating of all ResourceProviders when their exclude path
> set changes was introduced to prevent non-deterministic behaviour of resource
> observation.
> This change though caused calling {{updateProviderContext()}} and
> {{ResourceProviderHandler#update()}} on every registered
> {{ResourceProviderHandler}} when a new ResourceProvider was
> activated/deactivated no matter if the paths actually intersect.
> This is quite resource consuming (processing time and memory) and should be
> reduced to update only those handlers that actually intersect with the
> handler added/removed.
