Embodiment Construction

[0058] The embodiment of the present application provides a data storage method and its device, which are used to generate a corresponding first index node according to the first data during data access, and the data granularity of the first index node is larger than the minimum data granularity, so there is no It is necessary to generate multiple index nodes corresponding to the smallest granularity, which saves storage resources and improves the efficiency of data reading and writing.

[0059] see figure 1 , is a schematic diagram of the framework of the metadata storage system provided by the embodiment of the present application.

[0060] An embodiment of the present application provides a metadata storage index framework. The data storage index framework includes a plurality of index nodes, and the corresponding relationship between different index nodes constitutes an index tree framework. Among them, as shown in the MGTree part, the root index node corresponds to the l...

Abstract

The embodiment of the invention discloses a metadata storage method. The method can be used in a storage system. The method comprises a first metadata storage unit and a second metadata storage unit, the size of the first metadata storage unit is larger than that of the second metadata storage unit, and when the size of target data reaches a set threshold value, metadata of the target data is stored according to the first metadata storage unit; or when the size of the target data is smaller than a set threshold value, metadata of the target data is stored according to a second metadata storage unit. According to the embodiment of the invention, corresponding metadata during data storage can be reduced, and storage resources are saved.

Description

[0001] This application claims the priority of the Chinese patent application with the application number 202010374530.8 and the application title "data processing method, device and storage device" submitted to the China Patent Office on May 06, 2020, the entire contents of which are incorporated by reference in this application middle. technical field [0002] The embodiments of the present application relate to the field of computer technologies, and in particular to a method and device for storing metadata. Background technique [0003] In a storage system, performance and cost are the key indicators pursued by the storage system. In order to provide rich storage features, an index relationship is established when data is stored, and the index relationship is used to manage the mapping relationship between the user's logical data space and the underlying storage pool or physical data space of the storage disk. [0004] When establishing a mapping relationship, the physi...
