I lost interest in DM mostly because of my open-commit-access policy. I mismanaged the project horribly.

Just because something was called "Session" (ala Hibernate) instead of "Unit of Work", people would claim it wasn't "pure".

The only real compromises for purity were for performance. You saw the same thing play out with ActiveRelation. Ruby is (or was at least) just too slow for complex patterns unless you wanted to pay a huge performance penalty. The kind of slow that materializing 10,000 models in an O/R Mapper would bring your app to it's knees and use hundreds if not gigabytes of RAM.

And since a large reason for writing DM in the first place was AR's miserable performance at the time, it needed to be fast.

Most of the community wasn't that interested in closing open issues. Not that I blame them. It's not fun. But I was burnt out.

During the end, ActiveRelation started development, making many of the same mistakes early DM did in the quest for purity. By that point I just wasn't feeling it anymore. I'd spent orders of magnitude more effort on writing an O/R Mapper than I'd ever hope to recover, and I felt like some of the ideas were fundamentally flawed. So I moved on.

If I were still doing Ruby, I'd be using Sequel though.
