  • Objective: you want a job chain to execute exclusively one order at a time.
    Subsequent orders should wait until their predecessor(s) have proceeded to the end of the job chain.
  • You could specify the attribute max_orders=1 for your job chain:
    • Additional orders will wait before the first job node of a job chain.
    • Such orders will start immediately after their predecessor passed the job chain.
    • The sequence of orders that have been added to the job chain will be respected.
