I think that this is a good idea, but I think it would be far better if you described your API in terms of the twisted.enterprise.adbapi API which exists today.


from twisted.enterprise import adbapi

dbpool = adbapi.NonBlockingConnectionPool(

queries = ('SELECT 1 FROM DUAL', 'UPDATE Foo WHERE bar = baz')

for query in queries:
    d = dbpool.runQuery(query)

The effort needed to make this proposed asynchronous db protocol work with adbapi would be pretty minor, I think.

Tell you what: If somebody implements this MySQL async protocol, I'll create a patch to make adbapi work with it.  Sound good?
