Sure. I did not disagree with the meat of what Jim said. I am not sure
it is possible to effectively execute what he wants to do, but I don't
think he is wrong at all.

The point of what I said was to make it very clear that Dimitri is
wrong. Saying MySQL sucks is not productive at all.

Different strokes for different folks. I never said that those
features are the only ones that matter. Do note that most of the
features I mentioned don't help one run a big farm. Covering indexes
are assumed to be everywhere at this point. Checksuming data on disk
is just a good practice. I can continue at length.

My point is that beating up on MySQL ("only get so far") is often
wrong, intellectually dishonest and a discredit to the community.
