Amen brother. You should never base your db decisions on either marketing copy _or_ HN know-it-all complainypants. :) We actually evaluated TokuMX extensively last year, pre pluggable storage engine. We might have pursued it if they had implemented a compatible oplog at the time, but with a migration path that consisted of dumping and importing production data -- and no way to re-elect the old primary if there were any production problems -- that made it simply a non-starter for me. They did eventually implement a compatible oplog, which was a good product decision, but the entire TokuMX engineering team recently quit Tokutek en masse so it's still not a great option in my book. Too bad.
