Abstract

Systems and methods of distributed storage are disclosed herein. A request to store data in a client computer is received. A request is sent from the client computer to a storage service to create a core object such that the core object can be created with a member entry to a member feed in the core object. The member feed can be indicative of one or more entities that are permitted to access to the core object. A message is received at the client computer with the core object. A replica of the core object on the client computer is created. The client computer can add the data as a data entry to a data feed in the core object. An updating message is sent to the storage service. The message can include a copy of the replica of the core object including the data entry.

Claims

1. A computer-implemented method of storing data at a storage service, comprising:

receiving a request to store data in a client computer;

sending a request from the client computer to a storage service to create a core object such that the core object can be created with a member entry to a member feed in the core object, wherein the member feed is indicative of one or more entities that are permitted to access to the core object;

receiving a message at the client computer with the core object;

creating a replica of the core object on the client computer, wherein the client computer can add the data as a data entry to a data feed in the core object; and

sending an updating message to the storage service, wherein the message includes a copy of the replica of the core object including the data entry.

2. The method of claim 1, wherein the core object is created such that a computer identifier corresponding to the client computer is added as a mappings entry to a mappings feed of the core object, wherein the mappings feed is indicative of one or more device that are permitted to access to the core object.

3. The method of claim 1, wherein the core object is created such that awareness data corresponding to the client computer is added as an awareness entry to a awareness feed of the core object, wherein the awareness feed is indicative of one or more subscribed events regarding the core object.

4. The method of claim 1, further comprising adding personal data as a personal data feed to a personal data feed of the core object, wherein the personal feed is only accessible to the member that originated the request for creation of the core object.

5. The method of claim 1, wherein the core object is created such that design data corresponding to is added as a design entry to a design feed of the core object, wherein the design feed is indicative of application specific design of the core object.

6. The method of claim 1, further comprising adding a title to the core object.

7. The method of claim 1, further comprising adding a description to the core object.

8. The method of claim 1, wherein creating a replica of the core object on the client computer comprises replicating all feeds of the core object.

9. The method of claim 1, wherein creating a replica of the core object on the client computer comprises replicating a subset of the feeds of the core object.

10. The method of claim 1, further comprising retrieving the data by accessing the replica of the core object on the client computer.

11. The method of claim 1, further comprising retrieving the data by accessing the core object in the storage service.

12. A computer-implemented method of storing data at a storage service, comprising:

receiving a request from a client computer to create the core object;

creating a core object in response to the request;

storing the core object in a core object database in association with a unique identifier;

adding a member entry to a member feed in the core object, wherein the member feed is a set of entries associated with the core object, wherein the member feed is indicative of one or more computing entities that are permitted to access to the core object, the member entry including a device identifier of the client computer from which the request to create the core object was received;

mapping the core object to the client computer by sending a message to the client computer with the core object such that the client computer creates a replica of the core object on the client computer, wherein the client computer can add a data entry to a data feed in the core object; and

receiving a message from the client computer that includes the data entry entered into the core object.

13. The method of claim 12, wherein the core object is created such that a computer identifier corresponding to the client computer is added as a mappings entry to a mappings feed of the core object, wherein the mappings feed is indicative of one or more device that are permitted to access to the core object.

14. The method of claim 12, wherein the core object is created such that awareness data corresponding to the client computer is added as an awareness entry to a awareness feed of the core object, wherein the awareness feed is indicative of one or more subscribed events regarding the core object.

15. The method of claim 12, further comprising adding personal data as a personal data feed to a personal data feed of the core object, wherein the personal feed is only accessible to the member that originated the request for creation of the core object.

16. The method of claim 12, wherein the core object is created such that design data corresponding to is added as a design entry to a design feed of the core object, wherein the design feed is indicative of application specific design of the core object.

17. The method of claim 12, further comprising adding a title to the core object.

18. The method of claim 12, further comprising adding a description to the core object.

19. The method of claim 12, wherein creating a replica of the core object on the client computer comprises replicating all feeds of the core object.

20. The method of claim 12, wherein creating a replica of the core object on the client computer comprises replicating a subset of the feeds of the core object.

21. A computer-readable medium that includes a core object data structure, comprising:

a metadata feed that includes a set of entries indicative of metadata associated with the core object;

a members feed that includes a set of entries indicative of entities that can access the core object;

a mappings feed that includes a set of entries indicative of devices in which the core object is replicated; and

a data feed that includes a set of entries that include the actual data stored by the core object.
