Static Dependencies* · Netflix/iceberg

Logical Decomposition #1: PRIMARY

The decompositions is based on the folder structure at level 1 (relative to the source code root).

Static Dependencies

Dependencies among components are static code dependencies among files in different components.

Analyzed system has 20 links (arrows) between components.
The number on the arrow represents the number of files from referring component that depend on files in referred component.
These 20 links contain 143 dependencies.

About This Analysis

Static code dependencies refer to the relationships between different modules, libraries, or components in a software system that are established at compile-time rather than at runtime. These dependencies are determined by the code itself, meaning that one module directly references another through imports, includes, or explicit references in the code. Examples include:

Library and Module Imports
Class Dependencies (Inheritance & Composition)
Function and Method Calls
Dependency Injection Without Runtime Resolution
