File metadata query method and system based on traceability information in storage system

Abstract

The invention discloses a method for inquiring file metadata in a storage system based on provenance information. The provenance information is collected at a system client side, and file correlation information is obtained through analysis and is transmitted to a metadata server; the metadata server maintains a relational graph in real time according to the relation information between files; a metadata index tree based on correlation perception is established; after an inquiring request is received, firstly a seed result set is found in the metadata index tree, then the relational graph is searched to obtain an initial result set, and lastly a final result obtained by ranking and simplifying the initial result set according to inquiring conditions is transmitted to a client. The invention further provides a corresponding system for inquiring the file metadata. According to the method and system, correlation properties between the files are evaluated through relation values, the characteristics of fast locating of a space index structure and the accurate correlation of the relational graph can be fully utilized, and the efficiency for metadata inquiring is optimized.

Description

technical field [0001] The invention belongs to the technical field of computer data storage, and more specifically relates to a file metadata query method and system based on traceability information in a storage system. Background technique [0002] Now metadata query research is becoming more and more important. There are two main reasons. One is that with the development of mobile networks and cloud computing, the data scale in information storage systems is getting larger and larger, and it is very difficult for users and system administrators. It is difficult to manage and locate the files you need, so you must use a fast and accurate query system to improve efficiency. On the other hand, compared with traditional data management, big data management pays more attention to data analysis. Through data analysis, users or administrators can better grasp the true value of data. Data analysis requires a large number of query operations. In modern storage systems, a special...
