Abstract: With the growth of data volume and increased query complexity, the need for the application of various optimisation techniques that enable faster execution and more efficient use of ...

Existing index tuners typically rely on the “what if” API provided by the query optimizer to estimate the execution cost of a query on top of an index configuration. Such cost estimates can be ...

Picture this: I’m hunched over a garage floor, scrubbing away at the gunky paint remover I’ve spread over a fire-engine-red paint to make way for the aesthetically-pleasing home gym that’s going to ...

Determining the degree of parallelism (DOP) for query execution is of great importance to both performance and resource provisioning. However, recent work that applies machine learning (ML) to query ...

Abstract: In today's complex world requires state-of-the-art data analysis over massive data sets. In data warehousing and OLAP applications, scalar-level predicates of set in SQL become highly ...

I'm on a project that inherited some old generalized metadata search code and it can get terribly bogged down speed-wise. It's a bit annoying wait a couple minutes for a search to run: an example ...
