Abstract

A computer implemented method includes receiving an object scheduled for automatic deletion after a specified viewing period, a specified number of views or a specified period of time. Object push criteria are evaluated. The object is pushed to an edge server cache in response to evaluating. The object is served in response to a request for the object.

Claims

1. A computer implemented method, comprising:

receiving an ephemeral object scheduled for automatic deletion after a specified viewing period, a specified number of views or a specified period of time, wherein the ephemeral object has a designated recipient;

evaluating object push criteria including behaviors observed through prior consumption of ephemeral objects by the designated recipient;

pushing the object to an edge server cache in response to evaluating, wherein pushing is performed speculatively prior to the designated recipient requesting the ephemeral object; and

ascribing a cache management rank to the object based upon available space at an edge server versus the probability the ephemeral object will be served from the edge server.

2. The computer implemented method of claim 1 further comprising serving the object from the edge server in response to a request for the object by the designated recipient.

3. The computer implemented method of claim 1 wherein the object is a message.

4. The computer implemented method of claim 1 wherein the object is a message with an accompanying picture.

5. The computer implemented method of claim 1 wherein the object is a message with an accompanying video.

6. The computer implemented method of claim 1 wherein the object push criteria includes content delivery network traffic patterns.

7. The computer implemented method of claim 1 wherein the object push criteria includes historical use patterns of a user.

8. The computer implemented method of claim 1 wherein the object push criteria includes a social graph associated with a user.

9. The computer implemented method of claim 1 wherein the object push criteria includes geolocation information.

10. The computer implemented method of claim 1 further comprising ascribing a cache management rank to the object based upon historical use patterns of the designated recipient.

11. The computer implemented method of claim 1 further comprising ascribing a cache management rank to the object based upon geolocation information of the designated recipient.

12. The computer implemented method of claim 1 further comprising deleting every instance of the object.

13. The computer implemented method of claim 12 wherein deleting is performed after serving the ephemeral object.

14. The computer implemented method of claim 12 further comprising checking for an object deletion problem.

15. The computer implemented method of claim 14 further comprising disabling an edge server in response to an object deletion problem.
