Time series data storage method and apparatus, and electronic device

Abstract

The invention discloses a time series data storage method and apparatus, a time series data query method, apparatus and system, and an electronic device. The time series data storage method comprises the steps of acquiring to-be-stored time series data as original time series data, wherein attributes of the original time series data include a data identifier attribute, a time attribute and a data value attribute; performing statistics processing on the original time series data with the same data identifiers and the time in a preset time interval according to at least one preset time interval, forming a time series data statistics value of at least one time granularity based on the same data identifiers, and storing the original time series data and the time series data statistics values of all the time granularities in a distributed database. By adopting the method, the data storage amount can be effectively reduced, so that the effects of saving storage space and increasing data query speed are achieved; and the time series data is stored in the distributed database, so that the extensibility of the storage space can be effectively improved.

Description

technical field [0001] The present application relates to the technical field of data processing, and in particular to a storage method, device and electronic equipment for time series data. The present application also relates to a query method, device and system for time series data, and yet another electronic device. Background technique [0002] The performance data on the machine is generated all the time, which is a typical time-series data (referred to as time-series data). Machine performance data needs to be stored for a long time, so that it is convenient to check the status trend of the machine within a specified time range during operation and maintenance, or check the detailed status at a certain moment. For example, by looking at the memory change trend of the application for a month, you can determine whether a memory leak has occurred; check the QPS at a certain moment to understand the pressure of the application at that moment. Performance indicators are ...
