In this series of videos, We want to discuss some performance aspects of ABAP CDS views. As a performance expert daily working on CDS view performance topics I hope to be able to give some insights from my experience.
To track the complexity of a CDS view, display the complexity metrics in ABAP Development Tools (ADT) we will use a static dependency tree in CDS Modeling area. In the Dependency Analyzer, the view hierarchy and complexity are visualized with 3 tools:
SQL Dependency Tree, SQL Dependency Graph, Complexity Metrics

▶ Core Data Service is also known as CDS is one of the integral parts of many SAP® Projects. Advantage of Using CDS are:
➜ With the help of Core Data Services, we can expose data in views
which are compatible with ABAP® Dictionary
➜ Transport CDS views across multiple systems
➜ We can perform complex queries and join operations and reuse
existing CDS views
➜ We can use CDS view inside the ABAP® program with AMDP to Take
Advantage of Performance of HANA® and Features of ABAP®
➜ CDS also come up with feature-rich annotations, with the help
of which we can expose CDS views as oData source in a few
simple steps
➜ All than and more gives you enough reason to learn and
understand CDS view
