Example Embodiment

[0038] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0039] The core of the present invention is to provide a local object management method, device, equipment, and medium. The present invention can promptly restore the Use the data segment of the aggregated file for storage, avoiding a large number of read and write operations on the disk during the process of transferring valid data, and reducing the impact on the actual read and write operations of the front-end business; and, by overwriting th...

Abstract

The invention discloses a local object management method. The method comprises the steps of creating an invalid data chain table used for recording attribute information of each aggregation file and position information of invalid data on the aggregation files; judging whether a writing instruction for writing the target data is received or not; and if yes, writing the target data needing to be written into the target invalid data segment corresponding to the target invalid data according to the position information recorded in the invalid data link table so as to cover the target invalid data. Therefore, the data segments of the aggregated file can be reused in time for storage, a large number of read-write operations generated by a disk in the process of transferring valid data are avoided, and the influence on the actual read-write operations of front-end services is reduced; extra load brought to the disk is avoided while quick release of the storage space is realized. In addition,the local object management device and equipment and the storage medium provided by the invention correspond to the method.

Description

technical field [0001] The present invention relates to the technical field of distributed storage, in particular to a management method, device, equipment and medium of a local object. Background technique [0002] With the rapid development of distributed storage technology, distributed storage has been widely used in various industries. In distributed storage, local object storage is at the bottom and is responsible for actually writing data to disk. In the object aggregation implementation of local object storage, all objects are written to an aggregate file in chronological order and appended. The default file size is 64MB, and it will automatically switch to a new aggregate file when it exceeds. Such a file will eventually be distributed to different aggregate files, and an aggregate file will also contain objects from different files. [0003] When modifying and writing a file, first append new data to the current aggregated file, and then set the corresponding data...
