US 2016/0241670 A1 · INSTANTANEOUS NON-BLOCKING CONTENT PURGING IN A DISTRIBUTED PLATFORM

Abstract

Some embodiments provide instantaneous and non-blocking content purging across storage servers of a distributed platform. When a server receives a purge operation, it extracts an identifier from the purge operation. The server then generates a content purge pattern from the identifier and injects the pattern to its configuration. Instantaneous purging is then realized as the server averts access to any cached content identified by the pattern. The purging also occurs in a non-blocking fashion as the physical purge of the content occurs in-line with the server's cache miss operation. The content purge pattern causes the server to respond to a subsequently received content request with a cache miss, whereby the server retrieves the requested content from an origin source, serves the retrieved content to the requesting user, and replaces a previously cached copy of the content that is to be purged with the newly retrieved copy.

Dependent claims

A computer-implemented method for non-blocking content purging, the method comprising:

caching a plurality of content to memory of a content distribution server;
receiving by the content distribution server, a command designating removal of particular content from said memory, wherein the particular content is part of the plurality of content cached to said memory;
maintaining a copy of the particular content in said memory in response to said command and before the content distribution server receives a user request for the particular content;
receiving by the content distribution server, a user request for the particular content;
and
executing by the content distribution server, a cache miss in response to the user request, wherein executing the cache miss comprises replacing the copy of the particular content in said memory with an updated copy retrieved from an origin server and sending the updated copy in answer to the user request.

A computer-implemented method for purging content across a distributed platform with a purge control server and a plurality of points-of-presence (PoPs) with each PoP of the plurality of PoPs comprising a plurality of storage servers, the computer-implemented method comprising:

receiving at the purge control server, a set commands requesting purging of a set of customer content from the distributed platform;
transmitting said set of commands from the purge control server to a first storage server of a first PoP of the plurality of PoPs and a second storage server of a second PoP of the plurality of PoPs;
distributing said set of commands from the first storage server to all other storage servers of the first PoP, and from the second storage server to all other storage server of the second PoP;
purging the plurality of customer content from the plurality of storage servers of the first and second PoPs;
and
propagating execution confirmation of said set of commands to the purge control server (i) from the first storage server after each storage sever of the plurality of storage servers of the first PoP completes said purging, and (ii) from the second storage server after each storage sever of the plurality of storage servers of the second PoP completes said purging.
