The point is that MongoDB writes/reads directly to File system. It could have been (and still could be retro-fitted) to ride on top of an RDBMS for all it's actual IO, and create a hybrid. I'm aware of all the orthogonal points you raised which have nothing to do with ruling out RDBMS as I/O

- ClayFerguson 10y agoWiredTiger is a great way to correct from the original 'wrong turn' mongo took when they decided not to build on an existing (RDBMS). WiredTiger may be vastly superior to the MySQL codebase, afaik, but i would tend to doubt it. And you know the code overlap would be at least 80%, in terms of what's going on, which proves my original thesis, which is they should have built on top of RDBMS to start with.
