Are your big queries using every available clock tick, or are they lagging behind? And if your queries are already going parallel, can they be rewritten for even greater speed? In this session you will learn how to take full advantage of parallelism.
Large, complex queries need memory in which to work--workspace memory--and understanding the how's, when's, and why's of this memory can help you create queries that run in seconds rather than minutes.
Attend this session to learn how to take charge of optimization, expertly mold your query plans, and gain a new set of tools for eliminating bottlenecks in even your most complex problem queries.
