Subject [jira] [Created] (OAK-1497) JackrabbitEvent#isExternal() returns true for internal changes for slow listeners
Date Wed, 05 Mar 2014 08:19:47 GMT
Michael Dürig created OAK-1497:
----------------------------------

             Summary: JackrabbitEvent#isExternal() returns true for internal changes for slow
listeners
                 Key: OAK-1497
                 URL: https://issues.apache.org/jira/browse/OAK-1497
             Project: Jackrabbit Oak
          Issue Type: Improvement
            Reporter: Michael Dürig
             Fix For: 0.18


Oak degrades gracefully for observation listeners that can't keep up with the rate of observation
events fired. See {{BackgroundObserver#contentChanged}} for the gory details. 

As a side effect {{JackrabbitEvent#isExternal}} will always return {{true}} when this degradation
happens. However there is currently no way for clients to detect this and to thus know whether
the result of {{JackrabbitEvent#isExternal}} is reliable or not.
