Embodiment Construction

[0026] The present invention will be further described below in conjunction with the accompanying drawings. The following examples are only used to illustrate the technical solution of the present invention more clearly, but not to limit the protection scope of the present invention.

[0027] like figure 1 As shown, a distributed storage method of a real-time database includes the following steps:

[0028] Step 1. When writing data, the data is divided into multi-level storage, and the data is first written into a fixed-size micro-memory component in a way of compressing the dead zone threshold.

[0029] The data is collected by each measuring point device, collected and input into the system through the network, and then distributed to several local computing nodes through concurrent scheduling. After the computing node receives the data, it is first written into a fixed-size micro-memory according to the compression method of the dead zone threshold in the component.

Abstract

The invention discloses a distributed storage method for a real-time database. The distributed storage method for the real-time database has following beneficial effects: continuous storage and access of the real-time database for processing data with super-high concurrency and high-frequency generation can be simultaneously acquired; data storage and historical data access can be simultaneously performed and mutual interference is reduced; efficiency of storage space is increased; speed of the real-time database for storage and access of historical data is increased; and the capability of efficiently and rapidly retrieving and inquiring is provided.

Description

technical field [0001] The invention relates to a distributed storage method of a real-time database, in particular to a distributed storage method of a real-time database used for storing historical data in a comprehensive monitoring system, and belongs to the technical field of real-time database storage. Background technique [0002] At present, the real-time data of the comprehensive monitoring system used in many fields is stored using a relational database. However, in many application scenarios, it is necessary to process massive concurrent and high-frequency time-series data, and it is increasingly difficult for relational databases to adapt to and meet the needs of integrated monitoring systems for historical data storage and processing. [0003] The design goal of the traditional database represented by the relational database is to maintain the correctness of the data, ensure the low cost of the system and provide a friendly user interface. This kind of database ...
