AI Technical Summary
Benefits of technology
The invention is a computing system that uses a file service proxy cache node to improve data processing efficiency. Specifically, the system allows for a data request to be passed between an upstream site and the file service proxy cache node, which saves the data in a stable memory and dispatches a flushing request to a second file service proxy cache node if necessary. This helps to ensure the data is always available for use and reduces processing delays. The technical effects of the invention include improved data processing speed and efficiency, as well as improved performance and reliability in data processing operations.
Problems solved by technology
Of course, pre-fetching is only performed for well-behaved clients.

Embodiment Construction
[0011]This Summary is provided to introduce a selection of concepts in a simplified form that are further described below in the Detailed Description. This Summary is not intended to identify key features or essential characteristics of the claimed subject matter, nor is it intended to be used as an aid in determining the scope of the claimed subject matter.
[0012]One example embodiment includes a computing system where a data request has been passed between an upstream site and a file service proxy cache node, the file service proxy cache node being a network node located between the upstream site and the origin file system node, a non-transitory computer-readable storage medium including instructions that, when executed by the file service proxy cache node, performs the step receiving a flush request from the upstream site. The flush request includes a request to save flush data contained in the flush request to a stable memory. The instructions also perform the steps storing the f...

Large scale high performance file proxy caching sites may be configured to coalesce many client write operations into one very large assemblage of modified file data. At some point the caching site will flush all modified file data downstream towards the origin file server. In some instances the amount of modified data being flushed may be more than can be transferred in a single network request. When multiple network requests are required, the consistency guarantee provided by many filesystems requires that the file either be updated with the data contained in all of the network requests or not be modified at all. In addition, once the first flush request is processed no other file read or write requests can be serviced until the last flush request has been processed. This document discloses methods for performing atomic multi-request flush operations within a large geographically distributed filesystem environment.
