Abstract

A system and method can support one or more named operations in a distributed data grid. The distributed data grid includes one or more cluster nodes that can provide the one or more named operations associated with one or more resources in the distributed data grid. The distributed data grid can publish the one or more named operations to a client. Furthermore, the distributed data grid can perform the one or more named operations in the distributed data grid upon receiving a request from a client.

Claims

1. A method for supporting a plurality of named operations in a distributed data grid operating on one or more microprocessors, comprising:

defining the plurality of named operations associated with one or more resources in the distributed data grid;

associating each of the plurality of named operations with a unique name;

publishing the plurality of named operations to a web client external to the distributed data grid; and

receiving a request from a said web client external to the distributed data grid, wherein the request includes a particular unique name of a particular one of said plurality of named operations;

performing the particular one of the plurality of named operations in the distributed data grid, in response to said request from said web client.

2. The method according to claim 1, further comprising:

defining each of the plurality of named operations in a configuration file for the one or more resources in the distributed data grid.

3. The method according to claim 1, further comprising:

allowing the web client to be a REpresentational State Transfer (REST) client,

allowing the request from the web client to be a Hypertext Transfer Protocol (HTTP) request which includes the particular unique name of the particular one of said plurality of named operations as part of a Uniform Resource Locator (URL), and

providing an HTTP response to the web client after performing the particular one of the plurality of named operations in the distributed data grid.

4. The method according to claim 1, further comprising:

providing a response to the client after performing the particular one of the plurality of named operations in the distributed data grid.

5. The method according to claim 1, further comprising:

providing a proxy service;

receiving said request with the proxy service; and

triggering said performing of said particular one of the plurality of named operations using said proxy service.

6. The method according to claim 1, wherein:

one of said plurality of named operations is a named query operation having a unique query name, and said request includes said unique query name; and

wherein said performing step comprises using a custom query engine to perform the named query operation on the one or more resources in the distributed data grid in response to said request.

7. The method according to claim 1, wherein:

wherein said performing step comprises using a custom query engine to perform the particular one of the plurality of named operations on the one or more resources in the distributed data grid.

8. The method according to claim 1, further comprising:

allowing at least one of said plurality of named operations to be performed using a named entry aggregator.

9. The method according to claim 1, further comprising:

allowing at least one of said plurality of named operations to be performed using a named entry processor.

10. The method according to claim 1, further comprising:

publishing the plurality of named operations to the client using a Web Application Description Language (WADL).

11. A system for supporting a plurality of pre-defined operations in a distributed data grid, comprising:

one or more microprocessors;

one or more cluster nodes in the distributed data grid running on the one or more microprocessors, wherein the one or more cluster nodes are configured to

define the plurality of named operations associated with one or more resources in the distributed data grid,

associate each of the plurality of named operations with a unique name,

publish the plurality of named operations to a web client external to the distributed data grid,

receive a request from said web client external to the distributed data grid, wherein the request includes a particular unique name of a particular one of said plurality of named operations, and

perform the particular one of the plurality of named operations in the distributed data grid, in response to said request from said web client.

12. The system according to claim 11, wherein:

the plurality of named operations are each defined in a configuration file for the one or more resources in the distributed data grid.

13. The system according to claim 11, wherein:

the client is a REST client, and wherein the request from the client is a HTTP request which includes the particular unique name of the particular one of said plurality of named operations as part of a Uniform Resource Locator (URL), and

wherein the one or more cluster nodes are further configured to provide an HTTP response to the web client after performing the particular one of the plurality of named operations in the distributed data grid.

14. The system according to claim 11, wherein:

the one or more cluster nodes are configured to provide a response to the client after performing the particular one of the plurality of named operations in the distributed data grid.

15. The system according to claim 11, further comprising:

a proxy service;

wherein said proxy service is configured to receive said request and trigger said performing of said particular one of the plurality of named operations using said proxy service.

16. The system according to claim 11, wherein:

one named operation of said plurality of named operations is a named query operation having a unique query name, and said request includes said unique query name;

wherein said one or more cluster nodes are configured to use a custom query engine to perform the named query operation on the one or more resources in the distributed data grid in response to said request which includes said unique query name.

17. The system according to claim 16, wherein:

said one or more cluster nodes are configured to use a custom query engine in the distributed data grid in response to said request which includes said particular unique name.

18. The system according to claim 11, wherein:

one of said plurality of named operations is performed using a named entry aggregator.

19. The system according to claim 11, wherein:

one of said plurality of named operations is performed using a named entry processor.

20. A non-transitory machine readable storage medium having instructions stored thereon for supporting a plurality of named operations in a distributed data grid, which instructions, when executed, cause a system to perform steps comprising:

defining the plurality of named operations associated with one or more resources in the distributed data grid;

associating each of the plurality of named operations with a unique name;

publishing the plurality of named operations to a web client external to the distributed data grid; and

receiving a request from said web client external to the distributed data grid, wherein the request includes a particular unique name of a particular one of said plurality of named operations;

performing the particular one of the plurality of named operations in the distributed data grid, in response to said request from said web client.
