Introduction to Cask Data Application Platform
The Introduction to Cask Data Application Platform (CDAP) course delivers the key
concepts and expertise needed to build real-time and batch applications on CDAP. This
course is comprised of a combination of lectures and labs to reinforce core concepts.
At the end of the course participants will be able to write CDAP applications, integrate
applications in their CI environments and possess the skills to test and debug
applications.
Course Duration
8 Hours
Audience & Prerequisites
