Abstract

The invention discloses a data storage method. The method comprises the following steps of dividing the to-be-stored data into a plurality of data sets; enabling each data set to establish a mapping relationship with a corresponding server node through a virtual storage space domain and a Harsh algorithm, namely storing each data set into the server node which has the mapping relationship with the data set. The automatic storage of massive data in a distributed real-time database system is realized, the data distribution workload of workers is reduced, and the distributing efficiency during data storage is improved. The invention also discloses a data inquiry method and a data storage system.

Description

technical field [0001] The present invention relates to the technical field of distributed real-time databases, more specifically, to a method and system for storing and querying data in a distributed real-time database system. Background technique [0002] In petrochemical, chemical and other fields, real-time database is the core data platform of modern large-scale process control system, which provides essential and efficient data services for upper-level applications such as enterprise benefit evaluation, process optimization, and management decision-making. In recent years, with the optimization of industrial structure and the improvement of concentration, the production scale of enterprises has continued to expand, and the requirements for the performance, reliability and scalability of real-time databases have become higher and higher, and distributed real-time database systems have been widely used. [0003] Although the current real-time database system can achieve ...
