The invention discloses a data distributed cache automatic loading and conversion method, and particularly relates to the technical field of databases. According to the method, an annular storage structure based on the existing consistent Hash distributed data is realized by adopting a consistent Hash uniform distribution cache mode; by adopting the feature extraction of the stored data, the data is converted into features, and a corresponding set database is created for the features; by adopting an independent search engine to index the content, the distributed big data is subjected to unified set indexing, so that the retrieval speed is increased, and meanwhile, according to the hyperchain correspondence of data nodes, a mode of accurately reading the data and synchronously cooperating with three layers of caches is formed; and for the cache data with timeliness, the cleared cache data is independently stored, the collection of high-frequency files is realized; through the distributed storage data calling again, the data pressure of the distributed storage is relieved to a certain extent, and meanwhile, the cache effect is further enhanced.
