Components & Dependencies

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).

Bubble Chart | Tree Map
Component Sizes (Lines of Code)
The "primary" logical decomposition has 9 components.
  • 528 files, 58,321 LOC (100.0% vs. main code).
  • "tez-dag" is biggest, containing 41.84% of LOC.
  • "tez-dist" is smallest, containing 0.12% of LOC.


tez-dag24403 LOC (41%) 209 files
tez-runtime-library13714 LOC (23%) 95 files
tez-mapreduce8296 LOC (14%) 63 files
tez-api7315 LOC (12%) 108 files
tez-runtime-internals2972 LOC (5%) 37 files
tez-common857 LOC (1%) 9 files

Static Dependencies
Dependencies among components are static code dependencies among files in different components.
  • Analyzed system has 25 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 25 links contain 440 dependencies.
  • There are 3 places (6 links) with cyclic dependencies (104 file dependencies).
