Problems solved by technology

Influx-proxy, as a cluster solution for time series database (influxdb), solves the problem that the stand-alone version of time series database cannot store massive data collected by devices
Because influx-proxy allocates the equipment to be stored for each time-series database in the time-series database cluster based on the hash algorithm to collect data, there is a problem that the amount of data stored in each time-series database in the time-series database cluster is seriously unbalanced

Embodiment Construction

[0044] In order to make the technical problems, technical solutions and beneficial effects solved by the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention, but not to limit the present invention.

[0045] The invention provides a time-series data storage method based on a dynamic weight-balanced time-series database cluster. Based on the method, the data collected by IoT devices can be evenly stored in each time-series database influxdb in the time-series database cluster, which is mainly used in the IoT The cloud of the system stores the scene of collecting data from massive IoT devices, refer to figure 1 , including the following steps:

[0046] Step 1, the time series database influxdb cluster is configured with the cluster interface influx-gate, the publis...

Abstract

The invention provides a time-series data storage method based on a dynamic weight-balanced time-series database cluster, comprising: a time-series database cluster configuration cluster interface, a publish-subscribe message system cluster, a reader and m time-series databases; For virtual buckets, the allocation interval segment is determined for each virtual bucket; the time-series database selection algorithm based on dynamic weight balancing time-series database cluster is used to determine the target time-series database and store the data. The present invention provides a time-series data storage method based on a dynamic weight-balanced time-series database cluster, which is used in a scenario where the cloud of the Internet of Things stores data collected by a large number of devices, and can solve the problem of storage space waste caused by serious unbalanced storage data of various time-series databases in the current cluster and clustering. Difficulty scaling out. Through the present invention, the data collected by the Internet of Things equipment can be uniformly stored in each time series database in the time series database cluster, thereby improving user experience.

Description

technical field [0001] The invention belongs to the technical field of time series data storage, and in particular relates to a time series data storage method based on a dynamic weight balancing time series database cluster. Background technique [0002] The IoT system needs to use the time series database in the cloud to store massive data collected by devices for application query and analysis. Influx-proxy, as a cluster solution for the time series database (influxdb), solves the problem that the single-machine version of the time series database cannot store a large amount of data collected by devices. Because influx-proxy allocates data to be stored by devices to collect data for each time series database in the time series database cluster based on the hash algorithm, there is a serious imbalance in the amount of data stored by each time series database in the time series database cluster. SUMMARY OF THE INVENTION [0003] In view of the defects existing in the pri...
