identify, for each of the product inventory update information messages, one or more servers, of multiple servers operated by each of the multiple application services, intended to receive the product inventory update information message;

wherein the causing each of the product inventory update information messages to be streamed to each of the multiple different application services comprises causing each of the product inventory update information messages to be streamed to the corresponding identified one or more servers intended to receive a respective product inventory update information message such that the product inventory update information messages are distributed amongst the multiple servers operated by each of the multiple application services.

9. The system of claim 1 , wherein at least some of the multiple product inventory update information messages each comprises a product inventory storage facility identifier that uniquely identifies the product inventory storage facility from which a product inventory update information message is received, and a product identifier that uniquely identifies a product for which the product inventory update information message corresponds.

10. The system of claim 9 , wherein each of the at least some of the multiple product inventory update information messages further comprises a data type wherein the data type comprises at least one of: a change in a quantity of the product in inventory at the identified product inventory storage facility, and a change in pricing at the product inventory storage facility corresponding to the product.

11. The system of claim 1 , comprising the multiple different application services wherein two or more of the multiple different application services comprise multiple application servers each configured to identify a subset of the product inventory update information messages corresponding to a partition of the inventory information for which the respective application server is responsible and update inventory information based on the respective subset of the product inventory update information messages.
