Is Pika thread safe?

Pika does not have any notion of threading in the code. If you want to use Pika with threading, make sure you have a Pika connection per thread, created in that thread. It is not safe to share one Pika connection across threads, with one exception: you may call the connection method add_*caback_*threadsafe from another thread to schedule a callback within an active pika connection. See connection adapter for more details.
