title: SQLAlchemy: is it possible to operate Query without bounding to session?
body: <p>I want to execute the same SQL query from different processes by SQLAlchemy.
  As I understand I must create new Session in every process. So for each new session I must recreate query:</p>
  
  <pre><code>session.query(...).filter(...)
  etc.
  </code></pre>
  
  <p>It seems logical to save fully formed query separately from session. And then only apply this query to each session:</p>
  
  <pre><code>new_session.query(old_saved_query)
  </code></pre>
  
  <p>Is it possible?
  Or there is some other way?</p>
