Subject [jira] [Commented] (DIRSERVER-1719) [Perf] Modify the way we process entries to be returned
Date Mon, 30 Apr 2012 12:38:50 GMT


Emmanuel Lecharny commented on DIRSERVER-1719:

This was exactly what I had in mind : wrap the entr fetched from the backend, and store there
the modification to be applied.

The tricky part comes with the ACI which may hide some attribute's values, so the granularity
is the value, not the attribute

> Right now, we clone the entries we will return to the client just after having fetched
them from the backend. This is necessary as we will remove and add some attributes and values
from those entries, to comply with the user request.
> Another idea would be to compute the attributes (and values) to return, and when done,
create a new entry with all those attributes.
> As a user rarely requires all the attributes (including the operational ones), this might
save some processing, as in the current system we copy all the attributes, then we remove
some of them.
> Even better, when the CoreSession is called from the LdapProtocol layer, we don't have
to copy the attributes at all, we just have to write on the socket only the required attributes.
This will be even faster than what we currently do.
