Problems solved by technology

However, this type of database does not have a data storage solution for the characteristics of historical data, so this type of database is not fully suitable for the storage requirements of historical data
[0005] To sum up, in the face of massive historical data, there is currently no complete and available implementation solution that can not only meet the current data storage requirements, but also ensure that the system has dynamic scalability to meet the continuously growing demand for data storage and processing

Embodiment Construction

[0027] In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings.

[0028] In order to solve the storage problem of massive historical data, the embodiment of the present invention provides a simple and efficient method for storing massive historical data files and an efficient distributed storage method based on the characteristics of distributed file systems that store large files in blocks. Index mechanism. The storage method can ensure that the storage requirements of the current massive historical data files are met, and it is also guaranteed to have the characteristics of online expansion. The index mechanism proposed in the embodiment of the present invention can realize fast access to massive historical data, and at the same time, after the system is expanded, that is, when the underlying physical storage changes, the inde...

Abstract

The invention discloses a method for storing and indexing mass historical data, which belongs to the field of a real-time historical database. By the method according to the characteristic that the partitioning storage of big files is carried out by a distributed type file system, a simple high-efficiency method for storing mass historical data files and a high-efficiency distributed type indexing mechanism are provided. According to the storing method, the condition of meeting the requirement of storage of the current mass historical data files can be ensured, and the characteristic of on-line expansion is further ensured; the quick access of the mass historical data can be realized by the indexing mechanism; and meanwhile, after the resource expansion of the system is carried out, i.e. when the change of the physical storage of a bottom layer occurs, the searching function of the data still can be realized by an index under the condition of no need for modification.

Description

Technical field [0001] The present invention relates to the field of real-time historical databases, in particular to a method for storing massive historical data in real-time historical databases and establishing index files for them. Background technique [0002] Real-time historical databases are widely used in the field of industrial control, and the industries involved include electric power, petroleum, metallurgy, and chemical industries. The real-time historical database uses measuring points as the basic unit to describe production data. A measurement point in a database corresponds to a physical data source in the real world, such as the voltage of a certain transmission line, the temperature of a certain detection point, etc. The data stored in the measuring point is a discrete quantity, and the stored data is time stamped. The production process data collected from the scene (such as the current and voltage at different parts of a certain equipment, the water level a...
