Yeah, what you'd like to be able to do is a SELECT
sum(cmis:contentStreamLength) from cmis:document where...
But you can't. :)
So you'll have to iterate. Couple of thoughts, though:
- Ask for the cmis:contentStreamLength specifically--don't use * if all you
need is that length property. That will speed up performance a bit.
- Be sure to use paging on the result set.
- Using IN_FOLDER will give you just the space taken up by that folder object.
If you want to recurse use IN_TREE instead.
