Large-file distributed caching system based on object storage

The invention discloses a large-file distributed caching system based on object storage, which relates to the technical field of file caching, and structurally comprises a system main body, a cachingplug-in, the object storage and a database, and the operation process of the large-file distributed caching system comprises two parts A and B, wherein the cache plug-in sends a query or storage request to a system main body. The system main body queries in a database according to the request and returns a query result of the database. And B, automatic management of the cache: automatically putting the cache into different areas of object storage based on comparison between cache occupied space and a trigger flow process threshold value and comparison between a cache heat value, a cache capacity and a deletion threshold value. According to the method, the experience of long-time-consuming operation such as multimedia processing can be improved, the existing object storage in the project can be fully utilized, the
