I swear, you guys are such buzzkills some days. I was suggesting a
model for building easy prototypes, and advocating a more formal way to
explain, in what could be code form, what someone means when they
suggest a particular quorum model or the like. Maybe all that will ever
be exposed into a production server are the best of the hand-written
implementations, and the scary "try your prototype here" hook only shows
up in debug builds, or never gets written at all. I did comment that I
expected faster built-in implementations to be the primary way these
would be handled.
From what Heikki said, it sounds like the main thing I was didn't
remember is to include some timestamp information to allow rules based
on that information too.
