Orders minions

The pending orders process is managed using scaled minions. 

The PendingOrdersMinionBoss is a scaled minion that watches the PendingOrdersList. It runs every 5 minutes and, using a round-robin algorithm, it distributes the items in its list to two childrenPendingOrderMinions for further processing.

There are two instances of the PendingOrdersMinion, defined as children of the PendingOrderMinionBoss: PendingOrders.1 and PendingOrders.2. Each pending order child minion watches its own list of pending orders passed on by the parent minion (PendingOrdersMinionBoss).

The PendingOrderMinionruns the IPendingOrdersMinionPipeline. This pipeline checks if all the order's lines are available and then performs the following:

If one of the order's lines is not available, the IPendingOrdersMinionPipeline moves the pending order to the WaitingForAvailabilityOrders list. The order's status changes from pending to WaitingForAvailability.

If a problem or situation interrupts the normal order process flow, the order status is set to Problem and the order is added to the Problem order list.

The WaitingForAvailabilityOrdersMinion watches the WaitingForAvailabilityOrders list and runs the IWaitingForAvailabilityOrdersMinionPipeline that performs availability checks on the line items included in the order.  Once items are in stock, the order is moved back to the PendingOrderslist. The order is put in the Pending status.

The WaitingForAvailabilityOrdersMinion runs every 5 minutes.

The ReleasedOrdersMinion watches the ReleasedOrdersList. It calls the IReleasedOrdersMinionPipeline and checks if the order is ready to be completed.

If the release order is ready, it generates the order’s shipments or entitlements and moves the order to the CompletedOrderList. The order’s status changes to Completed.

The ReleasedOrdersMinion runs every 5 minutes.

The SettleSalesActivitiesMinion watches the SettleSalesActivities list. It calls a pipeline that settles the orders payments.

The SettleSalesActivitiesMinion runs every 5 minutes. It calls the ISettleSalesActivityPipeline.

The RefundRmasMinion watches the RefundPendingRmas list.  It calls the IRefundRmasMinionPipeline that processes Refund Authorization Requests and refunds the orders payments for order with returned items.

The RefundRmasMinion runs every 5 minutes.
