[12:52] <jtv> mgz: hi — would you be a good person to ask about the Tag model code in MAAS?
[12:53] <mgz> yeah
[12:54] <jtv> Excellent.  I was wondering why TagManager.get_nodes essentially duplicates NodeManager.get_nodes.  Was there a performance problem with the ordering of SQL "WHERE" constraints or something?
[12:56] <mgz> not that I recall, probably just we weren't sure which would be more useful and ended up with both
[12:56] <jtv> I suppose there would have been a comment if there were some compelling nonobvious reason...  I think I'll just eliminate the redundancy then.  Thanks.
[12:57] <jtv> Could also be that it was written without a good "feel" for how filtering in this particular ORM works.
[12:58] <mgz> I'd certainly expect tag getting nodes and getting nodes filtered on tag to generate equivalently performing sql
[12:59] <jtv> Yes, ultimately the DB back-end ought to transform past any such ordering dependencies.
