Grouped writes seem more or less equivalent to write barriers in terms of their semantics, but probably with 1 less syscall - which is nice. But I'd take any of these approaches over years of discussion & no solutions. I wonder what it would take to actually implement this stuff in linux. A lot of work, sure - but far from impossible. Thanks for lmdb btw! The design is lovely. I've used it in a couple projects, and I had a read through your code for inspiration while I was designing out a little storage engine for something I've been working on. Its delightful.
