ZODB BTree optimizations

Project description

Introduction

This library provides experimental code to speed up BTree difference and intersection functions, as used by the ZCatalog.

It’s been extracted out from experimental.catalogqueryplan now that the query plan implementation has been moved to ZCatalog itself.

Testing

To test, import the monkey patch in other tests, like CMFPlone:

import experimental.btree

and run the test.

Development

Development of this project takes place at: https://github.com/Jarn/experimental.btree
