This presentation builds on Recorded Webcast # 49911 Explaining the EXPLAIN, which did just that (if you have not viewed, please do so before this class).
Now, having completed that course, you should already have familiarity with the following Teradata EXPLAIN Facility features: how and where the text is generated; how to read the output; what spool sizes and estimated time (cost) really represent; choices that can be made to affect the optimizer; confidence levels; and joins.
In this session, we will cover new features available in TD 14 and TD 14.10, including what to look for when accessing a columnar table, Incremental Query Processing (IPE) and the Partial Redistribution Partial Duplication join strategy for skewed data.
Presenter: Alison Torres, Director, Teradata Labs Customer Briefing Team - Teradata Coroporation
