Abstract

The invention provides a low-efficiency SQL statement analysis method and system based on a distributed database cluster. By setting an SQL performance analysis model, the function of automatically analyzing the input SQL statements can be realized, wherein the SQL performance analysis model is formed by carrying out training according to historical data; and application data and system data are both known data, the known data serve as the basis of performance results, and the analysis results tend to be reasonable day by day through training. Manpower can be liberated, efficiency can be improved, and analysis and diagnosis of a low-efficiency SQL can be completed quickly.

Description

technical field [0001] The present invention relates to the technical field of database query, and more specifically, relates to an inefficient SQL statement analysis method and system based on distributed database clusters. Background technique [0002] In most cases, distributed databases are more suitable as storage engines, computing engines, and analysis engines for big data. For example, Greenplum, as an enterprise-level database product, has the advantages of "supporting massive data storage and processing", "high cost performance", "supporting BI real-time analysis", "realizing dynamic data warehouse", "system ease of use", and "using MPP parallelism". The processing structure supports thread expansion", "good concurrency support and high availability support", "supports MapReduce", "database internal compression" and other characteristics, which can be said to be one of the most advanced OLAP open source databases in the world. [0003] A distributed database is a ...
