[jira] [Commented] (OAK-775) Implement backward compatible observation

["Michael Dürig (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/OAK-775?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13646614#comment-13646614 ] 

Michael Dürig commented on OAK-775:
-----------------------------------

To better understand the backwards compatibility issues associated with observation in Oak, I added additional logging at revision 1478014:
* Each registered and re-registered observation listener is logged at debug level along with its filter parameters using the marker {{observation}}.
* Each call to {{Event.getUserId}} and {{Event.getUserData}} is logged at warning level using the marker {{deprecation}}.

> As [discussed | http://markmail.org/message/6bqycmx6vbq7m25c] we might want look into implementing an alternative approach to observation, which trades some scalability for improved backward compatibility.
