(I know you won't believe this, Theo, but ...)
I agree with Theo!
:-)
I do think the distinctions between these various special indexes are
potentially important and well worth the effort of getting right; but
I also think we need to make sure that people who are throwing
together quick clients don't have to think about these subtleties
unless they want to. It seems obvous to me that the hidden subtext of
serverChoice is "Just Do The Right Thing, Dammit!", so whatever other
indexes we end up adding to the "cql" set, I suggest that we have a
big, bold banner saying "If you don't know or care which of these to
use, just use serverChoice". (Which of course is equivalent to not
specifying an index at all.)
