Problems solved by technology

[0003] However, in the usage scenario of a large amount of data, Druid faces a problem, that is, when Druid obtains the metadata of the data block segment from the target underlying database (such as MySql) after receiving the query command, the target underlying database is not necessarily the client The underlying database of the corresponding server, and the obtained segment metadata needs to be transmitted through the network, and the network transmission bandwidth is fixed. Therefore, the larger the amount of data obtained, the slower the transmission speed, and it will take a long time to transfer the data from The target underlying database is transferred to the client, reducing the performance of Druid

Abstract

The invention discloses a data management method and device, electronic equipment and a computer readable storage medium, and the method comprises the steps: obtaining metadata of data blocks of all underlying databases in a cluster, and storing the metadata of all data blocks to a cache device of a server node; determining a query target according to the state of the cache device; when a query instruction is received, obtaining metadata of a data block corresponding to the query instruction from a query target and feeding the metadata back to the client, wherein the query target is a cache device or a target underlying database. According to the method and device, the execution link of the query instruction can be shortened, the transmission time consumption of metadata of the data block in the network is reduced, and the performance of the Druid is improved.

Description

technical field [0001] The present application relates to the server field, in particular to a data management method, device and related components. Background technique [0002] Druid is a high-performance real-time analysis database that can provide sub-second query data storage for historical and real-time data. Druid supports low-latency data ingestion, flexible data exploration and analysis, high-performance data aggregation, and simple horizontal expansion. It is suitable for analytical query systems with large data volumes and high scalability requirements. It is used in digital advertising analysis and business intelligence. , OLAP (Online Analytical Processing, Online Analytical Processing) and other fields are widely used. [0003] However, in the usage scenario of a large amount of data, Druid faces a problem, that is, when Druid obtains the metadata of the data block segment from the target underlying database (such as MySql) after receiving the query command, ...
