Abstract

The invention provides a method and device for managing a time series database. Specifically, the method is used for establishing indexes for time series in the time series database. The method includes dividing the time series in the time series database into a plurality of subseries; establishing spatial indexes corresponding to the subseries, and allowing the spatial indexes to determine the spatial spaces of the subseries in the time series; establishing content indexes for the subseries, and allowing the content indexes to determine the content ranges of the subseries in the time series. The invention provides the querying method in the time series database. The method includes on the basis of the spatial indexes, searching the corresponding spatial positions of the queried series in the time series of the time series database; on the basis of the content indexes, acquiring the content ranges of the subseries in the researched spatial positions; responding to consistence of the acquired content ranges and the content ranges of the acquired series, and outputting the subseries of the researched spatial positions.

Description

technical field [0001] Various embodiments of the present invention relate to database management, and more particularly, to methods and devices for managing a time series database (Time Series Database). Background technique [0002] With the development of computer, data communication and real-time monitoring technology, time series database has been widely used in many aspects such as equipment monitoring, production line management, financial analysis and so on. A time sequence (Time Sequence) refers to a collection of measured values ​​arranged in chronological order. Here, the node storing the measured values ​​can be called a data point (Data Point) or a data event (Data Event). A time-series database refers to the database used to store these measurements. Measured values ​​may include various data, for example, in the application environment of monitoring bridge safety, the collected data may include pressure data and / or pressure data collected by specific sensors;...
