Distributed multi-phase batch job processing

A distributed job-processing environment including a server, or servers, capable of receiving and processing user-submitted job queries for data sets on backend storage servers. The server identifies computational tasks to be completed on the job as well as a time frame to complete some of the computational tasks. Computational tasks may include, without limitation, preprocessing, parsing, importing, verifying dependencies, retrieving relevant metadata, checking syntax and semantics, optimizing, compiling, and running.

Optimizing parameterized queries in a relational database management system

Parameterized queries are optimized by a transformational optimizer. The optimizer produces a dynamic plan that embeds multiple plan options that may be selected to execute a particular query.

Exploiting partitioning, grouping, and sorting in query optimization

An optimizer uses comprehensive reasoning regarding partitioning, sorting, and grouping properties for query optimization. When optimizing an input query expression, logical exploration generates alternative logical expressions. Physical optimization explores physical operator alternatives for logical operators. Required partitioning, sorting, and grouping properties of inputs to physical operators are determined. Additionally, delivered partitioning, sorting, and grouping properties of outputs from physical operators are determined. In some embodiments, enforcer rules are employed to modify structural property requirements to introduce alternatives for consideration. Property matching identifies valid execution plans in which the delivered partitioning, sorting, and grouping properties satisfy corresponding required partitioning, sorting, and grouping properties. An execution plan having the lowest cost is selected as the optimized execution plan.
