---------------------------------------
Summary: Improve handling of updates to mapping (alias, vanity
path)
Key: SLING-3505
URL: https://issues.apache.org/jira/browse/SLING-3505
Project: Sling
Issue Type: Improvement
Components: ResourceResolver
Affects Versions: Resource Resolver 1.1.0
Reporter: Carsten Ziegeler
The update handling for the mapping including aliases and vanity path is a
simple algorithm which simply updates the whole mapping. Especially with large
mapping info spread across the repository, a simple update of a single property
results in the whole mapping info to be recreated.
It would be great if this could be improved.
Right now, only the active mapping is hold in memory - as a change of a single
property might cause to activate a totally different mapping than the one which
was changed (e.h. when the ordering is changed), the update needs to be more
complex or more information needs to be hold in memory.
In addition there is more to consider, like if the vanity path info is changed,
only the new value is available - but the old is gone.
