Optimize TPCH Queries with PawSQL
Overview
TPCH is a database test benchmark for decision support systems，developed by TPC (Transaction Processing Performance Council) in 1994. TPCH tests consist of a set of 22 complex business queries and some data maintenance queries to measure the performance of relational database management systems under complex analytical queries. These queries simulate real queries in a data warehouse of a wholesale supplier, covering aspects such as order analysis, supply chain management, and partial sales analysis.
Database vendors use TPCH tests to evaluate their products, assessing the impact of different servers, storage configurations, parallel processing, and resource scheduling on database performance.
In this article, we will evaluate the effectiveness of PawSQL's optimizations on the TPCH queries by only rewriting queries and recommending indexes without changing the hardware configuration and database parameters.
