We will start by introducing the Zero ETL concept: 

-      what does it really mean? 

-      what are the impacts, pros and cons for real life implementations?

-      when a Zero-ETL approach is convenient and when it is just impracticable. 

After this introduction we will analyze how can we fulfill the basic requirements behind Zero ETL approach by using existing Vertica capabilities to build a simple & robust data stack reducing both implementation and operational costs.
