Abstract

A controller receives a request from a user to store content in a target node of a plurality of nodes. A determination is made of a preferred node for the user, from a repository that maintains a correspondence between the user and the preferred node for storing the content for the user, wherein the preferred node is included in the plurality of nodes. Responsive to determining from that the determined preferred node is the target node, the controller transmits the request from the user to store the content, to the preferred node. Responsive to determining that the determined preferred node is not the target node, the controller transmits the request and an identification of the target node to the preferred node.

Claims

1. A method, comprising:

receiving, by a controller, a request from a user to store content in a target node of a plurality of nodes, wherein the target node is indicated in the request from the user;

in response to receiving the request, determining, by the controller from a repository that maintains a correspondence between the user and a preferred node for storing the content for the user, the preferred node for the user, wherein the preferred node is included in the plurality of nodes;

determining, by the controller, whether the determined preferred node is the target node indicated in the request from the user;

responsive to determining by the controller that the determined preferred node is the target node, transmitting, by the controller, the request from the user to store the content, to the preferred node, wherein in response to receiving the transmitted request from the controller, the preferred node stores the content in the preferred node; and

responsive to determining by the controller that the determined preferred node is not the target node, transmitting, by the controller, the request and an identification of the target node to the preferred node, wherein in response to receiving the transmitted request and the identification of the target node from the controller, the preferred node initiates a request to the target node and transfers the content to the target node.

2. The method of claim 1, wherein:

the preferred node is more proximate to the user for processing commands from the user, in comparison to other nodes of the plurality of nodes.

3. The method of claim 2, wherein the user is a first user, and wherein the preferred node of the first user is different from a preferred node of a second user.

4. The method of claim 1, wherein:

the plurality of nodes supports an access interface for updating and accessing the content; and

the plurality of nodes comprises a content management system supporting database management system (DBMS) transactions.

5. The method of claim 1, wherein the content includes data or objects, and wherein creating, reading, updating, and deleting of the content is performed in the plurality of nodes.

6. The method of claim 1, wherein the controller comprises a controller application that executes in a content management system comprising the plurality of nodes.

7. A system, comprising:

a memory; and

a processor coupled to the memory, wherein the processor performs operations, the operations comprising;

receiving a request from a user to store content in a target node of a plurality of nodes, wherein the target node is indicated in the request from the user;

in response to receiving the request, determining, from a repository that maintains a correspondence between the user and a preferred node for storing the content for the user, the preferred node for the user, wherein the preferred node is included in the plurality of nodes;

determining whether the determined preferred node is the target node indicated in the request from the user;

responsive to determining that the determined preferred node is the target node, transmitting the request from the user to store the content, to the preferred node, wherein in response to receiving the transmitted request, the preferred node stores the content in the preferred node; and

responsive to determining that the determined preferred node is not the target node, transmitting, the request and an identification of the target node to the preferred node, wherein in response to receiving the transmitted request and the identification of the target node, the preferred node initiates a request to the target node and transfers the content to the target node.

8. The system of claim 7, wherein the system is a controller.

9. The system of claim 8, wherein:

the preferred node is more proximate to the user for processing commands from the user, in comparison to other nodes of the plurality of nodes.

10. The system of claim 9, wherein the user is a first user, and wherein the preferred node of the first user is different from a preferred node of a second user.

11. The system of claim 8, wherein:

the plurality of nodes supports an access interface for updating and accessing the content; and

the plurality of nodes comprises a content management system supporting database management system (DBMS) transactions.

12. The system of claim 8, wherein the content includes data or objects, and wherein creating, reading, updating, and deleting of the content is performed in the plurality of nodes.

13. The system of claim 8, wherein the system is a controller that comprises a controller application that executes in a content management system comprising the plurality of nodes.

14. A computer program product, the computer program product comprising a computer readable storage medium having computer readable program code embodied therewith, the computer readable program code configured to perform operations, the operations comprising:

receiving, by a controller, a request from a user to store content in a target node of a plurality of nodes, wherein the target node is indicated in the request from the user;

in response to receiving the request, determining, by the controller from a repository that maintains a correspondence between the user and a preferred node for storing the content for the user, the preferred node for the user, wherein the preferred node is included in the plurality of nodes;

determining, by the controller, whether the determined preferred node is the target node indicated in the request from the user;

responsive to determining by the controller that the determined preferred node is the target node, transmitting, by the controller, the request from the user to store the content, to the preferred node, wherein in response to receiving the transmitted request from the controller, the preferred node stores the content in the preferred node; and

responsive to determining by the controller that the determined preferred node is not the target node, transmitting, by the controller, the request and an identification of the target node to the preferred node, wherein in response to receiving the transmitted request and the identification of the target node from the controller, the preferred node initiates a request to the target node and transfers the content to the target node.

15. The computer program product of claim 14, wherein:

the preferred node is more proximate to the user for processing commands from the user, in comparison to other nodes of the plurality of nodes.

16. The computer program product of claim 15, wherein the user is a first user, and wherein the preferred node of the first user is different from a preferred node of a second user.

17. The computer program product of claim 14, wherein:

the plurality of nodes supports an access interface for updating and accessing the content; and

the plurality of nodes comprises a content management system supporting database management system (DBMS) transactions.

18. The computer program product of claim 14, wherein the content includes data or objects, wherein creating, reading, updating, and deleting of the content is performed in the plurality of nodes, and wherein the controller comprises a controller application that executes in a content management system comprising the plurality of nodes.
