I'm wondering how people deal with migrating persistent objects that have changed.
I'm specifically interested in Java and serialization, but the discussion should be pretty general.
Q: What's the best scheme for saving objects and for migrating them when they have changed in a way that has broken serialization.
- Some ideas include not using serialization, but then again, you have the same issues to deal with.
A:
Q: If you serialize the objects and their codebases change, is there a simple way to update the codebase for those objects?
A:
I'd like this to turn into a set of best practices for Versioning Persistent Objects.
Possible solution bound to start a flamewar, but it is an option to consider: don't use heavy OO. Talk directly to the database instead of through object wrappers.
