Order states durable queuing apparatus and method
A synchronization server for fulfilling orders under non-persistent network conditions is provided. The server includes a terminal update element and a queue processor. The terminal update element receives state changes corresponding to one or more orders from one or more of a plurality of POS terminals. The queue processor queues the state changes in a plurality of durable terminal queues that correspond to the plurality of POS terminals, where the state changes are accessed by the terminal update element and are transmitted to a first one of the of plurality of POS terminals, from oldest to youngest, when the first one of the plurality of POS terminals is operably connected to the network, and where the state changes are maintained in durable terminal queues corresponding to other ones of the plurality of POS terminals while the other ones of the plurality of POS terminals remain operably disconnected from the network.
1. A synchronization server for fulfilling orders under non-persistent network conditions, comprising:
a terminal update element, configured to receive state changes corresponding to orders from POS terminals, wherein a first portion of said state changes correspond to a first portion of said orders that are transmitted through a gateway by a first portion of said POS terminals and a second portion of said state changes correspond to a second portion of said orders that are transmitted by a second portion of said POS terminals, and wherein the synchronization server is not on-premise with said POS terminals; and
a queue processor, coupled to said terminal update element, configured to queue said state changes in durable terminal queues that correspond to said POS terminals, wherein said state changes for all of said orders are accessed by said terminal update element and are transmitted to a first one of said of POS terminals, from oldest to youngest, when said first one of said POS terminals is operably connected to said network, and wherein said state changes are maintained in durable terminal queues corresponding to other ones of said POS terminals while said other ones of said POS terminals remain operably disconnected from said network.
2. The synchronization server as recited in claim 1 , wherein said network comprises the internet.
3. The synchronization server as recited in claim 2 , wherein the synchronization server comprises a cloud-based server.
4. The synchronization server as recited in claim 3 , wherein two or more of said POS terminals are configured to generate unique ones of said state changes corresponding to a same one of said orders.
5. The synchronization server as recited in claim 4 , wherein a first subset of said POS terminals operably connect to said network via one or more Wi-Fi access points that are disposed within a retail facility.
6. The synchronization server as recited in claim 5 , wherein a second subset of said POS terminals operably connect to said network via a wired connection disposed within said retail facility.
7. The synchronization server as recited in claim 6 , wherein a third subset of said POS terminals operably connect to said network via one or more cellular access points.
8. A synchronization server for fulfilling orders under non-persistent network conditions, comprising:
a terminal update element, configured to receive state changes corresponding to from POS terminals, wherein a first portion of said state changes correspond to a first portion of said orders that are transmitted through a gateway by a first portion of said POS terminals and a second portion of said state changes correspond to a second portion of said orders that are transmitted by a second portion of said POS terminals, and wherein the synchronization server is not on-premise with said POS terminals;
a queue processor, coupled to said terminal update element, configured to queue said state changes in durable terminal queues that correspond to said POS terminals, wherein said state changes for all of said orders are accessed by said terminal update element and are transmitted to a first one of said of POS terminals, from oldest to youngest, when said first one of said POS terminals is operably connected to said network, and wherein said state changes are maintained in durable terminal queues corresponding to other ones of said plurality while said other ones of said POS terminals remain operably disconnected from said network; and
a terminal status element, configured to periodically transmit a first message over said network to each of said POS terminals and update corresponding connectivity states based upon whether they acknowledge said first message or not.
9. The synchronization server as recited in claim 8 , wherein said network comprises the internet.
10. The synchronization server as recited in claim 9 , wherein the synchronization server comprises a cloud-based server.
11. The synchronization server as recited in claim 10 , wherein two or more of said POS terminals are configured to generate unique ones of said state changes corresponding to a same one of said orders.
12. The synchronization server as recited in claim 11 , wherein a first subset of said POS terminals operably connect to said network via one or more Wi-Fi access points that are disposed within a retail facility.
13. The synchronization server as recited in claim 12 , wherein a second subset of said POS terminals operably connect to said network via a wired connection disposed within said retail facility.
14. The synchronization server as recited in claim 13 , wherein a third subset of said POS terminals operably connect to said network via one or more cellular access points.
15. A method for fulfilling orders under non-persistent network conditions, comprising:
within a synchronization server:
receiving state changes corresponding to orders from POS terminals, wherein a first portion of the state changes correspond to a first portion of the orders that are transmitted through a gateway by a first portion of the POS terminals and a second portion of the state changes correspond to a second portion of the orders that are transmitted by a second portion of the POS terminals, and wherein the synchronization server is not on-premise with the POS terminals;
queuing the state changes in durable terminal queues that correspond to the POS terminals;
accessing and transmitting the state changes for all of the orders to a first one of the of POS terminals, from oldest to youngest, when the first one of the POS terminals is operably connected to the network; and
maintaining the state changes in durable terminal queues corresponding to other ones of the POS terminals while the other ones of the POS terminals remain operably disconnected from the network.
16. The method as recited in claim 15 , wherein the network comprises the internet.
17. The method as recited in claim 16 , wherein the synchronization server comprises a cloud-based server.
18. The method as recited in claim 17 , wherein two or more of the POS terminals are configured to generate unique ones of the state changes corresponding to a same one of the one or more orders.
19. The method as recited in claim 18 , wherein a first subset of the POS terminals operably connect to the network via one or more Wi-Fi access points that are disposed within a retail facility.
20. The method as recited in claim 19 , wherein a second subset of the POS terminals operably connect to the network via one or more cellular access points.
