[jira] [Created] (SLING-7544) Make optimized alias lookup non-blocking

Dominik Süß created SLING-7544:
----------------------------------

             Summary: Make optimized alias lookup non-blocking
                 Key: SLING-7544
                 URL: https://issues.apache.org/jira/browse/SLING-7544
             Project: Sling
          Issue Type: Improvement
          Components: ResourceResolver
    Affects Versions: Resource Resolver 1.5.36
            Reporter: Dominik Süß


The implementation of optimized alias lookup as introduced with SLING-2521 blocks CommonResourceResolver activation while loading aliases to fillup the aliasmap. In case a corresponding index is not present yet this can lead to full tree traversal while indexing is doing the same in the background.

The proposed improvements are:
* making loading of the aliasmap happen asynchronously
* only use optimized handling as soon as aliasmap is built
* wait for non traversal index (optional - forced by default, can be turned off for small datasets)
