Subject [jira] Closed: (CAY-294) Low memory footprint IncrementalFaultList
Date Thu, 11 Jun 2009 07:13:07 GMT


Andrus Adamchik closed CAY-294.

    Resolution: Won't Fix

The idea to swap out pages from the resolved list was floated multiple times... We may still
come to it at some point, although it is not that straightforward. In any even this specific
patch is already way out of sync with trunk.

> I have created a patch file (attached) for the stuff I have done on "memory reducing"
the large data set iteration.
> Note: I have basically tapped into the work you had done on tracking new objects in the
data store. If the user is using this to reduce memory already, then I enhance the loop processing
to revert the list's previous batch to the contents it had prior to being filled in (i.e.
a data row). This really cuts down on the memory.
> Andrus: That's a nice enhancement. I need to analyze this some more before commiting
to Cayenne.. For now storing it in JIRA.
