Problems solved by technology

[0005] Both B-tree (or its optimization algorithm) and hash table are recognized as excellent query algorithms, which are widely used in databases and file systems. However, in the case of extreme pursuit of space utilization and query efficiency, there are still additional space overhead and specific In case query efficiency is not the best issue

Embodiment Construction

[0039] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention clearer and clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0040] Such as figure 1 Shown is a flow chart of a file indexing method provided by an embodiment of the present invention. The method is applied to a cloud control server and includes:

[0041] S101. Establish and initialize an index in memory.

[0042] Specifically, the index includes: an array of file information with a predetermined length and a structure of file information, where:

[0043] The file information array is an array of pointers to the file information structure with a predetermined length;

[0044] The file information structure is ...

Abstract

The invention discloses a cloud control server and a file index method. The method comprises the following steps: establishing an index in a memory and initializing, modifying the information of a mapping relation and a data block of the memory index when the data block is written into a client side, and acquiring a marker of a cloud storage server where the required data are located from the memory index and feeding the maker back to the client side when the client side requires to read the data block. Due to the adoption of the cloud control server and the file index method, the index is loaded into the memory; compared with the mode of a database, the occupied space is reduced, meanwhile, and the speed of modifying and inquiring a file is accelerated, so the reading and writing efficiencies of the cloud storage data are improved.

Description

technical field [0001] The invention relates to the technical field of computer and network information, in particular to a cloud control server and a file indexing method thereof. Background technique [0002] With the continuous development of computers and networks and the popularity of high-definition video, the space required to store multimedia continues to grow, and traditional storage architectures have been difficult to meet the demand. Cloud storage has gradually emerged with its massive storage space, high reliability, high concurrency, high scalability and high cost performance. [0003] B-trees are data structures that store sorted data and allow lookup, sequential read, insertion, and deletion with O(log n) running time. B-tree, in general, is a binary search tree in which a node can have more than 2 child nodes. Unlike self-balancing binary search trees, B-trees optimize the read and write operations of large blocks of data for the system. The B-tree algori...
