This is an issue that I (and I think Brian) were asking about some time ago, but I can't seem to find any final resolution to it in the threads surrounding it in the mail archive. The basic question is "How can you store a derived view?".
At one point I thought that you could do something clever with view.union(), but all of these operations just create another derived view. Is there no simple way to (a) create a derived view and (b) put it in a storage? Is the only way to do this to create the new storage, the new view, and then populate the view with a row-by-row copy via append()?
Is there a way to use append() (via the Python wrapper) with a row object instead of a sequence or keyword/value arguments?
What I'm currently faced with is a very large storage (about 2.5 million rows) and I would initially like to "subset" this into another storage file.
Beyond that, it looks as though I'll ultimately be looking at a storage with that many rows and, say 20,000 properties per row. And I'll want to create and save derived views from that as well.
Suggestions?
