Problems solved by technology

This type of time series database organizes data according to columns, but these time series databases generally do not support column type changes
The business requirement that the IoT platform cannot support the change of the field type of the sensor data well
[0004] Therefore, the existing time series data storage and query methods have the technical problem of not being able to support the type change of time series data

Abstract

The invention provides a time series data storage method and device, and a time series data query method and device. The query method comprises the following steps: receiving data of to-be-stored time series data; judging the data type of the time sequence data according to the character features corresponding to the time sequence data; based on the working condition fields and the data type of the time sequence data, establishing a mapping relation between the working condition fields and a first type of column type storage unit of the time sequence database; based on the mapping relationship, storing each working condition data to the corresponding first-class column type storage unit, and according to a pre-established name corresponding relationship between the non-working condition field and the second-class column type storage unit, storing the non-working condition data to the second-class column type storage unit; and associating the working condition data in the same time sequence data with the non-working condition data in the time sequence database. The method does not depend on a time sequence database of a bottom layer, the storage unit to be written is determined according to the time sequence data, and data loss caused by equipment model evolution is avoided.

Description

technical field [0001] The present application relates to the field of computer technology, and in particular to a storage method, query method and device for time series data. Background technique [0002] The data generated by IoT devices usually has time-series characteristics, that is, time-series data, and there are various types of IoT devices, and the type of time-series data that each type of device can process may be different. Therefore, when replacing a device, if the data type of the new device is different from the type of data stored in the replaced device, it is necessary to change the field type of the data, and the data stored in the original device is different from that of the replaced device. The data uploaded by the device needs to be coherent. In addition, the model of the Internet of Things device also has a gradual evolution and maturity process. The definition of the device model will be continuously revised, including the change of the type of the ...
