    refactor: use short-lived sessions when accessing the database · 0b594e50
    Lars Kruse authored
    Previously the database connection ("DB.session") was established during
    the startup of Aura Engine.
    This was causing conflicts in the threaded execution environment (#75).
    Now all sessions are acquired in a short-lived context:
      with DB.Session() as session:
    If database query performance is a real concern, then the session
    contexts could be moved to a higher level.
    Closes: #75
