Abstract

The embodiment of the invention discloses a processing method for ranking records and a querying method for ranking and a related device and system. The processing method for the ranking records comprises the steps that a first ranking main record, corresponding to a first ranking type, of a first catalog is obtained and stored; the incidence relation between the ranking type identification corresponding to the first ranking type and the main record version number corresponding to the first ranking main record is recorded in a catalog main record corresponding to the first catalog; the mapping relation between the key of the first ranking main record and the storing address of the first ranking main record is recorded; the key of the first ranking main record comprises the main record version number corresponding to the first ranking main record. According to the technical scheme, the improvement of foreign consistency control performance of single dimensional ranking and multiple dimensional ranking of a subobject under the catalog is facilitated.

Description

Technical field [0001] The present invention relates to the technical field of file management, and specifically mainly relates to a processing method of sorting records, a sorting query method, and related devices and systems. Background technique [0002] In scenarios such as distributed file systems, the sorting display of sub-objects under a directory (sub-objects under a directory may include files and / or sub-directories) is a key to the directory service of the virtual file system provided to users technology. Among them, how to effectively design the data structure and storage method of the sorted data of the sub-objects under the directory to satisfy the user's multi-latitude sorting of the sub-objects under the directory is a key technical point of index design. Technical Difficulties. [0003] Especially for large catalog scenarios, when the number of sub-objects under a catalog reaches tens of thousands or more, by splitting the directory index storage method, the posi...
