Been reading through tons of old threads about varying transaction file implementations. As many of the discussions are old (some over a decade) what is considered the best way of implementing today? It appears that o_direct is frowned upon, is the current preferred mechanism to use mmap and basically append pages + partial sync when writing (one issue with the second is that it doesn't work in say windows where as o_direct does)?
We currently follow the added constraints mentioned by Linus in an old email (lost link) in that we use o_direct but prealloc and only use o_direct when reading. Is it worth looking at a mmap implementation?
