Course Overview
This two-day course teaches students how to manually build projections that aggregate or rearrange data on disk, thereby improving performance of queries that reference aggregated data. These projection types are not created by the Database Designer.
- The course uses videos and a series of hands-on labs to teach the course material.
- The intended audience for this course includes database administrators, product managers, and quality assurance team members. The course assumes students have the attained, at a minimum, the knowledge contained in the Vertica Essentials course; information contained in the Projection Tuning course would also be helpful.
- The content in this course is covered in the Vertica Analyst certification exam.
Highlights
- How to build and test the following projection types:
- Projections with expressions
- Live aggregate projections
- TopK projections
- Partition range projections
- The advantages and disadvantages of each of these projection types
Who should attend
Database administrators, product managers, and quality assurance team members
Prerequisites
To be successful in this course, you should have the following prerequisites or knowledge:
