Abstract: Join order selection is one of the most challenging problems in query optimization and plays an essential role in providing high query performance in Big Data management. Currently, ...

Hash join build takes majority of time(1.406s) in the following query. We can apply the semi-mask optimization in such case to minimize the number of tuples on the build side. kuzu> profile CALL query ...

The best CRM article on Page 1 might lose to a single paragraph buried on Page 3. That’s how AI search works now, and it’s why traditional SEO strategies are failing businesses that should be winning.

Abstract: This paper describes an implementation of Kruskal's algorithm in query optimization process for generation of a near optimal execution query tree. The open source Post- greSQL DBMS was used ...

The performance of a query crucially depends on the ability of the query optimizer to choose a good execution plan from a large space of alternatives. With the discovery of algebraic transformation ...

SQL is the de facto query language used to interact with databases. Since SQL is declarative, users express the intended result of their query rather than the concrete procedural steps to produce the ...

Our funcletizer identifies captured variables in the incoming query tree (member accesses over compiler-generated closure types), and converts these to ParameterExpressions which represent external ...

Modern database systems rely on cost-based query optimizers to come up with good execution plans for input queries. Such query optimizers rely on cost models to estimate the costs of candidate query ...
