Résumé du cours
This three-day course teaches students how Vertica executes queries, and how they can improve the performance of query execution by identifying execution issues in execution plans, and creating projection designs that address those issues.
- The course includes a series of hands-on labs to teach the course material.
- The content in this course is covered in the Vertica Analyst certification exam.
Highlights:
- Reading and interpreting a query execution plan
- Automatic projection optimization using the Database Designer
- Manual table and projection design to optimize for specific query execution
- Overriding default configurations to improve query performance
Moyens d'évaluation :
- Quiz pré-formation de vérification des connaissances (si applicable)
- Évaluations formatives pendant la formation, à travers les travaux pratiques réalisés sur les labs à l’issue de chaque module, QCM, mises en situation…
- Complétion par chaque participant d’un questionnaire et/ou questionnaire de positionnement en amont et à l’issue de la formation pour validation de l’acquisition des compétences
A qui s'adresse cette formation
