What is the relationship between the extending object and the object being extended if conflicts arise?

The extending object takes precedence over the object being extended in LookML when conflicts arise. This means that if there are overlapping definitions or conflicting parameters, the properties defined in the extending object will override those in the base object. This behavior is crucial for maintaining clarity and control over how the extensions modify or enhance the base definitions.

For instance, when a view or model is extended to add additional fields or modify existing ones, the intention is usually to customize or add functionality without altering the original base. Therefore, Looker prioritizes the extending object, allowing developers to refine the behavior and attributes of the original without losing the foundational structure.

This precedence model is fundamental for developers, as it simplifies the process of evolving data models while maintaining a clear control hierarchy and reducing the likelihood of introducing errors or conflicts in the data infrastructure.
