Working with it for a month or so now, certain things have come to light, the most deadly of which is its death spirals, a bad transaction comes in and then BOOM, it slows down, the transaction might be too big so it keeps stepping backing off to try again later, but it will never get smaller so it will never execute, it will just sit there being all destructive and mopey.
Darkstar is also too much of a black box, too much magic happens behind the scenes and as a result when it does death spiral you cannot do anything but sigh, blow out your database and restart it, which really isn't acceptable for any application.
I am really hoping that when Darkstar actually finishes that these problems get resolved as after all it is still in its beta phase because as a technology it seems pretty damn cool, but for our needs it is no longer viable.
