Re: [Zope] Finding a match in a large dataset - btrees?

[Andreas Jung]

--On 5. Dezember 2005 16:57:03 +1300 Cameron Beattie <[EMAIL PROTECTED]> wr> I've read a bit about btrees on the zope wiki and wonder if that's the

best way. However I am struggling with the basics:
1. How do I get the data from MySQL into a btree in Zope? Something like:
from BTrees.IIBTree import *
t = IIBTree()
t.update(context.select_from_LOCATION_MATCH) # errr, no

Reading helps:

2. How do I find the matching node i.e. when I want to know that 6422
relates to location_id 15?

I still have no idea what your example should tell me. A BTree basically

relationship (when using an IIBTree).

implements the same API as a Python dictionary. If you can implement your solution in pure Python then you can just switch to BTrees. But I have no idea about your example especially BTrees implement a 1:1
