An overview of source code logical components.

Intro

Logical decomposition is a representation of the organization of the main source code, where every and each file is put in exactly one logical component.

Logical Decompositions Overview

Analyzed system has 1 logical decomposition:

Logical Decomposition #1: PRIMARY

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

Component Sizes (Lines of Code)
The "primary" logical decomposition has 16 components.
  • 568 files, 63,439 LOC (100.0% vs. main code).
  • "parquet-column" is biggest, containing 28.59% of LOC.
  • "parquet-scala" is smallest, containing 0.08% of LOC.

Static Dependencies
Dependencies among components are static code dependencies among files in different components.
  • Analyzed system has 30 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 30 links contain 387 dependencies.
  • There is 1 place (2 links) with cyclic dependencies (61 file dependencies).
