Re: [ZODB-Dev] Plone in P2P using Zope over DHT

2011-01-06 Thread Aran Dunkley
Hi guys, It's looking like Plone/ZODB would need too much modification and testing at the current time to move in to P2P. The most promising environment in our research so far are frameworks built on the Squeak language which is used by the OpenCobalt project (a P2P collaborative 3D world).

Thanks for the feedback Vincent :-) it sounds like NEO is pretty close to being SQL-free. As one of the NEO team, what are your thoughts on the practicality of running Plone in a P2P environment with the latencies experienced in standard DHT (such as for example those based on Kademlia)

I'm not very optimistic about this I'm afraid. First the problems with using Plone: * Plone relies heavily on its in ZODB indexes of all content (portal_catalog). This means that every edit will change lots of objects (without versioning ~15-20, most of which are in the catalogue). * At least

I mean P2P as in using a DHT (distributed hash table) for its storage layer so that it can run in a network composed only of the client users with no web-server, the same way that the file-sharing programs such as azzureus and aMule work. We can develop a basic wiki/blog in this way, but would

Hey Andreas, I don't know much about Aran's project, so you are right to wonder the necessity to have yet another storage backend. Maybe he has needs and requirements that can't be fulfilled by the current backends. Aran, can you fill us in a little on the necessity of having a DHT ? What are

I have looked at NEO which is the closest thing I've found to the answer, in fact NEO is why I felt Plone was the best choice of CMS to inquire further about The problem is that it uses SQL for its indexing queries (they quote NoSQL as meaning Not only SQL). SQL cannot work in P2P space, but can
