Abstract

The invention provides a query and storage method, device and equipment based on a database cluster, and relates to the technical field of computers, in particular to the field of big data and database management. The specific implementation scheme is as follows: determining target index information according to a query condition of a query request; determining a target storage area corresponding to the target index information from a plurality of storage areas by utilizing a root index server; determining a target storage node corresponding to the target index information from a plurality of storage nodes included in the target storage area; and sending the query request to the target storage node to obtain target data. According to the technology disclosed by the invention, the query efficiency and the query accuracy are improved, and the utilization rate of a database cluster on computing resources is improved.

Description

technical field [0001] The present disclosure relates to the field of computer technology, in particular to the field of big data and database management technology. Background technique [0002] At this stage, the Internet of Things technology is booming and will generate a large amount of time-series data. One of the main problems faced by large-scale time-series database clusters is the data flood. Due to the characteristics of high-speed data writing and continuous updating, it is not suitable for index maintenance. In this context, in order to undertake a large number of queries, it is particularly important to quickly lock the node range of data in the cluster and control query fan-out in large-scale clusters. Contents of the invention [0003] The disclosure provides a database cluster-based query and storage method, device and equipment. [0004] According to an aspect of the present disclosure, a database cluster-based query method is provided, including: [000...
