[SLING-2521] Improve performance of sling:alias lookups and/or provide the ability to disable this feature

• Type: New Feature
• Status: Closed
• Priority: Major
• Resolution: Fixed
• Affects Version/s: JCR Resource 2.1.0
• Fix Version/s: Resource Resolver 1.0.0
• Component/s: JCR

Description

The the JCR based ResourceResolver.resolve method currently support sling:alias properties on nodes to allow for resolution of translated URLs. This is potentially a very expensive operation particularly in the case of non existing resource.

It should be analyzed whether (a) disabling sling:alias support has a measurable benefit on resource resolution (particularly when not finding a resource) and (b) whether it would be easy and simple to disable such support per configuration.
