Does Publisher and Subscriber is on same thread
<p>This is for just get an clarification on pub/sub + threading. </p>

<p>Doubt I have is 
In normal publisher/subscriber pattern does both subscribers and publisher is running on same thread or in different threads?</p>

<p>Or is it depend on implementations?</p>

<p>What I have in mind so far is  different subscription would have it is own threads whereas publisher run on it is own thread?</p>
