Abstract

Techniques are disclosed for storing content in distributed computing environments to reduce storage overhead and improve efficiency and/or speed of accessing and delivering the stored content. A content management system (or other authoring system, such as a text editor) supplies hints about dependencies among objects or files, such as which objects are embedded into a web page and which objects are referenced by the web page. These hints are then used when deploying the corresponding files on a storage system, such that the files which are likely to be retrieved together are (preferably) stored together. Optionally, run-time observations by a web server may be used as input to this process to determine how best to store content during a subsequent redeployment.

Claims

1. A method of storing content in a computing network, comprising:

generating by a content authoring tool a plurality of files and hints that specify one or more of the files that are likely to be referenced within a temporal proximity of reference to a selected other one of the files;

receiving at a storage system the plurality of files and hints from the content authoring tool; and

using the received hints to allocate storage within the storage system for the files.

2. The method according to claim 1, wherein the selected file is a web page.

3. The method according to claim 2, wherein the one or more files that are likely to be referenced within a temporal proximity of reference to the selected file comprise at least one of (1) one or more embedded objects of the web page and (2) one or more other web pages which are hyperlinked to the web page.

4. The method according to claim 1, wherein the selected file is a text document.

5. The method according to claim 4, wherein the one or more files that are likely to be referenced within a temporal proximity of reference to the selected file comprise one or more objects which are embedded within or referenced by the text document.

6. The method according to claim 1, wherein the hints further specify weights which describe a degree of dependency that the one or more files will be referenced within a temporal proximity of reference to the selected file.

7. The method according to claim 1, wherein the hints are encoded in a markup language notation.

8. The method according to claim 7, wherein the markup language notation is Extensible Markup Language (“

XML”

) notation.

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

receiving a request for one of the files at the storage system;

retrieving the requested file from the allocated storage within the storage system; and

returning the retrieved file responsive to the request.

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

using the received hints to create dependency information which is stored by the storage system in temporary or permanent storage;

receiving a request for one of the files at the storage system; and

determining a read request strategy for the requested file by accessing the stored dependency information.

11. The method according to claim 10, wherein the read request strategy comprises determining selected ones of the files which should be pre-fetched along with a read of the requested file.

12. The method according to claim 11, wherein determining selected ones of the files which should be pre-fetched further comprises comparing a dependency weight of the files to a pre-fetch threshold.

13. The method according to claim 12, wherein the pre-fetch threshold is used to tune the pre-fetch operation.

14. The method according to claim 11, further comprising:

retrieving the requested file from the allocated storage;

retrieving the selected ones of the files which should be pre-fetched from the allocated storage;

returning the retrieved requested file responsive to the request; and

caching the pre-fetched files.

15. The method according to claim 14, further comprising caching the retrieved requested file.
