Abstract

The embodiment of the invention provides a search method and device of a data block. The search method of the data block comprises the following steps of: obtaining a height value of a path tree on which a to-be-searched data block is located and a data management structure number corresponding to the to-be-searched data block; and searching an indicator corresponding to the data management structure number according to the height value of the path tree and the data management structure number, and positioning the to-be-searched data block according to the searched indicator. The embodiment in the invention can rapidly position the to-be-searched data block through the path tree, and improves the search efficiency of the to-be-searched data block.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a method and device for searching data blocks. Background technique [0002] If the file is stored on the disk, when reading and writing the file, it is first necessary to locate the file from the disk and read it into the memory before performing related processing. When the target file is large and only a part of the data in the target file needs to be read and written randomly, the process of finding specific data in the target file will consume a considerable amount of time. [0003] Moreover, in some applications, only a certain part of the data in the file is often processed. Generally, the processing speed is very fast, but the process of finding the data to be processed will consume a lot of time. How to quickly find the data to be processed is very important for improving The overall performance of the file system is critical. [0004] A method for searching dat...
