Abstract

Apparatus, systems, and methods may operate to receive a first service request for data from a user application executing on at least one first machine and, in response to the receiving, synchronously transmit a service request identification to the user application in reply to the first service request, as well as dispatching the first service request as an additional request to an application layer executing on at least one second machine. Further activities may include notifying the user application that a second response, including the data, is available for consumption (after receiving a response to the additional request), receiving a second service request from the user application, along with the service request identification, and synchronously transmitting the second response to the user application in reply to the second service request. Additional apparatus, systems, and methods are disclosed.

Claims

1. An apparatus including a processing node, the processing node comprising:

a data reception module to receive a first service request for data from a user application executing on at least one first machine; and

a communications module to communicate with the data reception module, the communications module being implemented by one or more hardware processors and being configured

to synchronously transmit a first response including a service request identification to the user application in reply to the first service request and to dispatch the first service request as an additional request to an application layer executing on at least one second machine,

to poll, based on the service request identification, the application layer for a second response to the additional request, responsive to dispatching the additional request to the application layer,

to receive the second response to the additional request, and to store the second response in a data structure in conjunction with the service request identification,

to notify the user application that the second response including the data is available for consumption, and

to receive a second service request from the user application, along with the service request identification, to access the second response from the data structure based on the service request identification received with the second service request, and to synchronously transmit the second response to the user application in reply to the second service request.

2. The apparatus of claim 1, further comprising:

a display module to display a user interface comprising a portion of the data.

3. The apparatus of claim 1, wherein the first service request and the second service request are stateless service requests, and wherein the additional request is an asynchronous request.

4. The apparatus of claim 1, comprising:

multiple processors, wherein the proecessing node comprises a first one of the multiple processors, wherein the communications module comprises a software module to be executed by a second one of the multiple processors, and wherein the processing node comprises one of a server or a client.

5. A system, comprising:

a first processing node comprising a data reception module to receive a first service request for data from a user application executing on at least one first machine; and

a second processing node comprising a communications module to communicate with the data reception module, the communications module

to synchronously transmit a first response including a service request identification to the user application in reply to the first service request and to dispatch the first service request as an additional request to an application layer executing on at least one second machine,

to poll, based on the service request identification, the application layer for a second response to the additional request, responsive to dispatching the additional request to the application layer,

to receive the second response to the additional request, and to store the second response in a data structure in conjunction with the service request identification,

to notify the user application that the second response including the data is available for consumption, and

to receive a second service request from the user application, along with the service request identification, to access the second response from the data structure based on the service request identification received with the second service request, and to synchronously transmit the second response to the user application in reply to the second service request.

6. The system of claim 5, wherein at least one of the first processing node and the second processing node further comprises a display module to display a user interface comprising a portion of the data.

7. The system of claim 5, wherein the first service request and the second service request are stateless service requests, and wherein the additional request is an asynchronous request.

8. The system of claim 5, wherein the first processing node comprises a first processor, wherein the communications module comprises a software module to be executed by a second processor, and wherein the first processing node comprises one of a server or a client.

9. A method, comprising:

receiving a first service request for data from a user application executing on at least one first machine;

in response to the receiving, synchronously transmitting a first response including a service request identification to the user application in reply to the first service request, and dispatching the first service request as an additional request to an application layer executing on at least one second machine;

polling, based on the service request identification, the application layer for a second response to the additional request, responsive to dispatching the additional request to the application layer;

after receiving the second response to the additional request, storing the second response in a data structure in conjunction with the service request identification;

notifying the user application that the second response, including the data, is available for consumption;

receiving a second service request from the user application, along with the service request identification;

accessing the second response from the data structure based on the service request identification received with the second service request; and

synchronously transmitting the second response to the user application in reply to the second service request.

10. The method of claim 9, farther comprising:

displaying a user interface comprising a portion of the data.

11. The method of claim 9, wherein the first service request and the second service request are stateless service requests, and wherein the additional request is an asynchronous request.

12. The method of claim 9, wherein the first service request is received at a processing node comprising a processor, and wherein the processing node comprises one of a server or a client.

13. The method of claim 9, wherein the first service request for data does not include the service request identification.

14. The method of claim 9, further comprising:

generating the service request identification, responsive to receiving the first service request for data,

wherein the service request identification uniquely identifies the first service request for data.

15. The method of claim 9, wherein the notifying includes transmitting a notification indicating that the second response corresponding to the service request identification is ready for consumption.

16. An article comprising a non-transitory computer-readable storage medium containing executable instructions stored thereon which, when executed, result in operations comprising:

receiving a first service request for data from a user application executing on at least one first machine;

in response to the receiving, synchronously transmitting a first response including a service request identification to the user application in reply to the first service request, and dispatching the first service request as an additional request to an application layer executing on at least one second machine;

polling, based on the service request identification, the application layer for a second response to the additional request, responsive to dispatching the additional request to the application laver;
