Re: [Zope-dev] difference between OOSet and OOTreeSet?

[Chris Withers]

Wondering if someone could tell me the difference between an OOSet and an OOTreeSet?

OOSet is to OOTreeSet as OOBucket is to OOBTree. An OOTreeSet is built out of leaf-level OOSets in exactly the same way an OOBTree is built out of leaf-level OOBuckets. More at: http://wiki.zope.org/ZODB/guide/node6.html#SECTION000630000000000000000

They seem to have different interfaces

?

and yet seem to be used in similar circumstances in PluginIndexes/common/UnIndex.py...

I'm looking for a set-like data structure which will likely get pretty large over time and so I don't want the whole data structure written to disk each time I add a new item to the set.

What should I be using?

OOTreeSet.
