             Summary: User defined property values in event info
                 Key: OAK-4853
                 URL: https://issues.apache.org/jira/browse/OAK-4853
             Project: Jackrabbit Oak
          Issue Type: New Feature
          Components: jcr
            Reporter: Marcel Reutegger


An event listener should be able to define a set of names of properties 
available in the info map of node events. This allows a listener to more 
efficiently process events, because it does not have to resolve the event path 
into a JCR item anymore. It would simply read the values of those properties 
from the event info map.

A similar feature was already implemented for property events: OAK-2262. 
However, there are also listeners that are interested in properties that did 
*not* change. One such application is Apache Sling, which heavily depends on 
properties like sling:resourceType. In many cases listener logic depends on the 
resource type and needs to know this value even if it didn't change.
