Abstract

The invention provides a Hadoop based power cloud data management indexing method in a power system. The method comprises: b. dividing received data into a mass data type and an information data type; c. establishing an index corresponding to each type according to the data types; and d. generating request information according to query conditions of a user, performing a search according to the request information, and feeding back a search result to the user. According to the method, the requirements of frequent updating and quick multi-dimensional query are effectively met, the influence of index creation on system writing performance is reduced to a certain extent, and the threat of retrieval to system stability is reduced.

Description

technical field [0001] The invention relates to the field of computers, in particular to a Hadoop-based power cloud data management indexing method in a power system. Background technique [0002] The safety and stability of power supply is the primary goal of the power sector. Today, as computer equipment continues to enter the power industry, with the rapid development of the Internet of Things, cloud computing, and mobile Internet, data is rapidly expanding in the form of explosion. The stability and security of power system data storage has become an important factor to ensure the stable operation of the power system. condition. [0003] In recent years, with the large-scale construction of infrastructure such as smart substations, the data volume of power grid enterprises is growing at a geometric rate, and its data sources are complex and diverse (structured, semi-structured and unstructured). features. Storage of various heterogeneous information, such as auxiliary...
