Are there any economy plugins which are fully transaction safe? Most economy plugins don't seem to be. What I mean is, if I call Account.add(player, money) in two separate threads, most economy plugins will fail to record the transactions correctly, and one of the two transactions will probably get lost. Ideally I'd like something that can do this without a global lock either. I know this is possible by using a transaction safe db (ideal) or using SQL table locks (less ideal), but none of the plugins seem to do this. Since none of them are transaction safe, that means I need to do all transactions in the main thread otherwise there is a potential to lose transactions. Say I want to send money to 100 people via some plugin. Each transaction is really, really slow, 3-6 ms. That's 10-30% of a tick just blocking on one transaction. Not a lot of CPU, just I/O blocking. That's awful. So, ideally I would want to do it in a separate thread so I/O doesn't block. Unfortunately, since none of them are transaction safe, I can't do this without risking losing data. If the answer is "no" (which I suspect is the answer), then it looks like I'm writing a transaction safe economy plugin.
