[Twisted-Python] IPushProducer - medium volume streaming

[Rutt, Benjamin]

This isn't a SQL db so I can't use adbapi.

So using deferToThread, inside my thread, when I have a result to write
to the client, I call callFromThread to schedule a write in the reactor
loop.  My question is, how exactly do I use callFromThread to write to
the client from the thread (I use the LineReceiver class)?
(specifically, what context do I pass to the thread func, to pass into
callFromThread call, to make sure it writes back to the right client?)

If this is a SQL database with which you're using a dbapi module, you
should probably be using twisted.enterprise.adbapi to make access to
that database asynchronous. Under the hood it's using threads to make
the interface asynchronous. Otherwise, if the only programmatic
interface this database of yours has is blocking, then you'll probably
need to use a thread yourself. See
twisted.internet.threads.deferToThread.
