I use this title at Andrei's suggestion, and repeat his idea that it be used as a prefix for discussions as we navigate toward a design. Unless there is resistance to the idea, I will on the job of implementing whatever we decide is appropriate. I am retired, and have the time to do it.
It seems that every man, and possibly his dog, has a private implementation for at least a favorite DB, so we should have plenty of material to build on. At this point I would like to get responses from those who feel they are likely to contribute to the design through to completion. I'd also like to get a feel for the magnitude of the task, so I'd like to ask what database systems you think should be supported. I have started a github account, and will put my mysqld stuff there shortly, then you can kick me out if you don't like what you see. Steve
