The data is a network of diverse related objects. I can keep the most-used objects in memory but not all of them. Indeed, I _need_ to keep them, otherwise this will be too slow, even when using Mongo instead of SQLAlchemy. Which objects are "most-used" changes over time. > Are you sure it won’t fit in memory? Default server memory configs these days tend to start at 128 Gig, and scale to 256 or 384 Gig. -Bill > I could work with MongoEngine by judicious hacking (augment DocumentField dereferencing with a local cache), but that leaves the update problem. > -- > https://mail.python.org/mailman/listinfo/python-list
