Abstract

The invention provides a Duid database data query method and device and computer equipment. The method comprises the steps: receiving a data query request of a user; according to the data query request, obtaining health states of multiple databases, wherein the multiple databases are deployed in different parks respectively; generating a query priority according to the health state of each database; according to the query priority, selecting the database with the optimal health state to perform data query to obtain a query result; and feeding back a query result to the user. According to the method provided by the invention, the health state of the Ruid database of each park can be obtained according to the data query request of the user, and the data query service is issued to the database with the best health state for processing, so that the condition of query failure is greatly avoided, and the query quality is improved.

Description

technical field [0001] The invention relates to the technical field of databases, in particular to a Druid database data query method, device and computer equipment. Background technique [0002] Druid database (Druid) is a distributed database, which can be widely used because of its ability to provide data query services with ultra-large data scale, millisecond-level delay, and excellent performance in data query with high real-time requirements. [0003] Druid is usually deployed in a single campus (also known as a data center). However, cross-campus deployment can greatly improve the high availability of Druid. Therefore, cross-campus Druid deployment has gradually attracted people's attention. In the prior art, cross-park Druid deployment usually adopts the following methods: 1. Distribute and deploy all Druid nodes in multiple parks; 2. Deploy Druid clusters in two parks, and then proxy the two Druid clusters through proxy devices. However, both of these two deploymen...
