Abstract

Disclosed in some examples are systems, methods, and machine readable mediums which provide a framework for client discovery of server features. In some examples, the client (e.g., the cloud service) may send a service request that requests data from the server (e.g., data source) processed according to one or more desired features from the server. The response from the data source may include feature indicators, which may indicate whether various features are supported at the data source.

Claims

1. A method comprising:

sending, from a network-based application, a service request to a data service including a request for data and a request for a desired feature of the data service, wherein the feature is performed on the data and related to a current context of the network-based application;

receiving, at the network-based application, a response from the data service including a plurality of feature indicators for the current context and the requested data;

determining, based upon at least one of the plurality of feature indicators, whether the desired feature is supported by the data service.

2. The method of claim 1, wherein sending the service request includes sending the request to a particular location of the data service defined by the current context of the network-based application.

3. The method of claim 1, wherein responsive to determining that the requested data is unmodified by the feature, executing the feature to modify the requested data on the network-based application.

4. The method of claim 1, wherein the plurality of feature indicators form a bitstream, each respective bit of the bitstream describing whether or not a particular one of a plurality of features is supported by the data service.

5. The method of claim 4, wherein the ordering of the feature bits is determined by a predetermined object structure.

6. The method of claim 1, wherein the network-based application is a cloud service.

7. The method of claim 1, wherein the network-based application stores the feature indicators received from the data service along with a plurality of other feature indicators from respective plurality of other data services.

8. A system comprising:

a service module configured to provide a network-based application;

an input and output module configured to;

send a service request to a data service including a request for data and a request for a desired feature of the data service, wherein the feature is performed on the data and related to a current context of the network-based application;

receive a response from the data service including a plurality of feature indicators for the current context and the requested data; and

a feature module configured to;

determine, based upon at least one of the plurality of feature indicators, whether the desired feature is supported by the data service.

9. The system of claim 8, wherein the input and output module is configured to send the service request to a particular location of the data service defined by the current context of the network-based application.

10. The system of claim 8, wherein the feature module is configured to execute the feature to modify the requested data responsive to determining that the requested data is unmodified by the feature.

11. The system of claim 8, wherein the plurality of feature indicators form a bitstream, each respective bit of the bitstream describing whether or not a particular one of a plurality of features is supported by the data service.

12. The system of claim 11, wherein the ordering of the feature bits is determined by a predetermined object structure.

13. The system of claim 8, wherein the network-based application is a cloud service.

14. The system of claim 8, wherein the feature module is configured to store the feature indicators received from the data service along with a plurality of other feature indicators from respective plurality of other data services.

15. A machine readable medium that stores instructions which when performed by a machine, cause the machine to perform operations comprising:

sending, from a network-based application, a service request to a data service including a request for data and a request for a desired feature of the data service, wherein the feature is performed on the data and related to a current context of the network-based application;

receiving, at the network-based application, a response from the data service including a plurality of feature indicators for the current context and the requested data;

determining, based upon at least one of the plurality of feature indicators, whether the desired feature is supported by the data service.

16. The machine-readable medium of claim 15, wherein the instructions for sending the service request include instructions, when performed by the machine, cause the machine to perform operations comprising:

sending the request to a particular location of the data service defined by the current context of the network-based application.

17. The machine-readable medium of claim 15, wherein the instructions comprise instructions, which when performed by a machine, cause the machine to perform operations comprising:

executing the feature to modify the requested data on the network-based application responsive to determining that the requested data is unmodified by the feature.

18. The machine-readable medium of claim 15, wherein the plurality of feature indicators form a bitstream, each respective bit of the bitstream describing whether or not a particular one of a plurality of features is supported by the data service.

19. The machine-readable medium of claim 18, wherein the ordering of the feature bits is determined by a predetermined object structure.

20. The machine-readable medium of claim 15, wherein the network-based application is a cloud service.

21. The machine-readable medium of claim 15, wherein the instructions comprise instructions, which when performed by a machine, cause the machine to perform operations comprising:

store the feature indicators received from the data service along with a plurality of other feature indicators from respective plurality of other data services.
