AI Technical Summary

Problems solved by technology

For a large amount of two-dimensional time series data, two-dimensional fast storage and query are required. When the amount of data surges in the traditional simple method, the query on a certain dimension will perform many I / O operations, and the efficiency is very low.

Abstract

The invention discloses a two-dimensional time-series data storage and query method based on periodic logs. The method is characterized in that (1) a multi-stage directory structure is provided; (2) the periodic logs service as indexes; (3) blocks are divided according to start and finish time. By the aid of the method, a large data can be stored as divided blocks, normal operation can be performed on the condition of small memory, the structure has high storing and querying efficiency on two dimensions, and the novel fast storing and querying method is applied to large data.

Description

technical field [0001] The invention relates to a two-dimensional time series data storage and query method based on periodic logarithm, which is suitable for the technical field of time series data storage and query. Background technique [0002] Two-dimensional time-series data mainly comes from a type of sensor that returns data according to a time period. This type of sensor will be installed on equipment that needs real-time monitoring, such as instrument panels, boilers, etc., and the attribute data of the monitoring equipment will be returned through the sensor, such as a certain The system can completely record the entire operating status of the equipment, such as the temperature at a moment, the pressure of the boiler, etc. When there is a problem with the equipment, it can analyze and locate the problem through the historical record. The current application development trend shows that the number of monitored individuals is growing rapidly, and with the advancement...
