Embodiment Construction

[0018] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments It is a part of embodiments of the present invention, but not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0019] Compared with relational databases, key-value (Key-Value) databases differ mainly in that the data format is not strictly defined. In a relational database, data definition is the constraint on data, including the relationship between data and the integrity of data. There is no strict data definition in the Key-Value database. For a certai...

Abstract

Embodiments of the present invention provide a method and a system of file access. The method comprises that: a file system driving module receives a first access request sent by an upper application; the file system driving module, according to the corresponding relation between an access interface corresponding to the upper application and an access interface of the key-value database, converts the first access request into a second access request which is suitable for access to the key-value database; the file system driving module sends the second access request to a client of the key-value database; and the client of the key-value database, according to the second access request, searches corresponding file content or directory entry content or file attributes or directory entry attributes from the key-value database which is stored in a server of the key-value database. When the technical schemes in the embodiments are compared with technical schemes of layer-by-layer access of metadata in file systems of POSIX in the prior art, access cost is relatively small and access efficiency is relatively high.

Description

technical field [0001] The embodiment of the present invention relates to the field of computer technology, and in particular to a file access method and system. Background technique [0002] In the prior art, a file system similar to Portable Operating System Interface for Unix / Linux (POSIX) includes metadata and data; wherein the metadata part includes file nodes ( inode) information to form a specific data structure (such as a multi-way search tree, etc.). The data part includes the content of the file. The POSIX file system can provide a POSIX interface to upper-level applications. Each directory and file in the POSIX file system has a corresponding file node (inode), which contains information such as the size of the file, creation and modification access time, permission attribution, and the address information of the file content in the data part. For a larger file, the distribution of its data part on the file system may be discontinuous, and may be composed of se...
