Revisioned Databases for MultiUser Editing (#86)


Revisioned Databases for MultiUser Editing

Presented by John Rittenhouse (CCP Games)

At CCP Games (, we work on large MMO projects with tens of content editors editing the same data. To make this possible, we created a Revisioned Database framework that allows for us to create new multiuser editing systems without data synchronization between users having to be a major concern. In this talk, solutions we've tried are discussed, the basic layout of our revision database shown, the Python layer which handles it transparently for the programmer detailed, and how the Python layer is used in practice. All of this is focused on discussing what worked well and what pitfalls we ran into during development.
