Hi. The ZODB currently uses a hardcoded pickle protocol one. There's both the more efficient protocol two and in Python 3 protocol 3. Protocol two has seen various improvements in recent Python versions, triggered by its use in memcached.
I'd be interested to work on changing the protocol. How should I approach this? I can see three general approaches: 1. Hardcode the version to 2 in all places, instead of one. Pros: Easy to do, backwards compatible with all supported Python versions Cons: Still inflexible 2. Make the protocol version configurable Pros: Give control to the user, one could change the protocol used for storages or persistent caches independently Cons: More overhead, different protocol versions could have different bugs 3. Make the format configurable Shane made a proposal in this direction at some point. This would abstract the persistent format and allow for different serialization formats. As part of this one could also have different Pickle/Protocol combinations. Pros: Lots of flexibility, it might be possible to access the data from different languages Cons: Even more overhead If I am to look into any of these options, which one should I look into? Option 1 is obviously the easiest and I made a branch for this at some point already. I'm not particularly interested in option 3 myself, as I haven't had the use-case. Thanks for any advice, Hanno _______________________________________________ For more information about ZODB, see the ZODB Wiki: http://www.zope.org/Wikis/ZODB/ ZODB-Dev mailing list - ZODB-Dev@zope.org https://mail.zope.org/mailman/listinfo/zodb-dev
