[Twisted-Python] deferToThread and thread pool
I have a few questions about the default implementation of deferToThread. 1. Does deferToThread use a thread pool by default? If not, how can I enable this? 2. Which thread are the callbacks and errbacks of the deferred returned by deferToThread run in? Thanks in advance! Brian

Yes
2. Which thread are the callbacks and errbacks of the deferred returned by deferToThread run in?
The reactor (i.e., probably the main) thread. -- Twisted | Christopher Armstrong: International Man of Twistery Radix | -- http://radix.twistedmatrix.com | Release Manager, Twisted Project \\\V/// | -- http://twistedmatrix.com |o O| | w----v----w-+

Yes. You can adjust the threadpool size using reactor.suggestThreadPoolSize: http://twistedmatrix.com/documents/current/api/twisted.internet.interfaces.I... http://twistedmatrix.com/projects/core/documentation/howto/threading.html#au...
2. Which thread are the callbacks and errbacks of the deferred returned by deferToThread run in?
The main thread, i.e. the reactor thread. -Andrew.
