I recomend you "durus" (http://www.mems-exchange.org/software/durus/)
and, depending of your usage profile, my storage backend:
<http://www.argo.es/~jcea/programacion/durus-berkeleydbstorage.htm>

Yes, durus supports transactions.

Durus is not async, but wrapping it in a thread should be easy enough.
I'm fairly involved with Durus, so I could help you there.
