DEPosit — Replication Package

DEPosit (Data Engineering Pipeline Repositories) is a dataset of open-source GitHub repositories in the data-engineering pipeline ecosystem.

The dataset contains a master cohort of 1,952 repositories together with repository activity, commits, pull requests, issues, CI-service information, contributor metrics, and pipeline discovery and feature data.

Dataset (Data/)

The Hugging Face Hub exposes each heterogeneous CSV table as a separate configuration. This prevents tables with different schemas from being incorrectly concatenated by the Dataset Viewer.

Configuration File Description
repositories filtered_DE_repositories.csv Master cohort (1,952 repos)
commits DE_all_commits_details.csv Commits per repository
pull_requests DE_all_pr_details.csv Pull requests
issues DE_all_issue_details.csv Issues
issue_closers DE_all_issue_closers.csv Issue closer logins
pr_reviews DE_all_pr_reviews_graphql.csv PR review / merge metadata (GraphQL)
ci_services DE_ci_services.csv Detected CI services per repo
ci_file_commits DE_commits_per_ci_files.csv Commits touching CI config paths
github_actions_runs DE_repo_gha_runs_counts.csv GitHub Actions run counts
repo_interactions DE_repo_interactions.csv Precomputed interaction-type metrics
repo_metrics DE_repo_metrics.csv Repo-level activity aggregates
user_autonomy DE_user_autonomy.csv Contributor autonomy per repo
pipeline_airflow pipeline_artifacts/DE_pipeline_airflow_dag_features.csv Airflow pipeline features
pipeline_beam pipeline_artifacts/DE_pipeline_beam_pipeline_features.csv Apache Beam pipeline features
pipeline_dagster pipeline_artifacts/DE_pipeline_dagster_features.csv Dagster pipeline features
pipeline_dbt_model pipeline_artifacts/DE_pipeline_dbt_model_features.csv dbt model features
pipeline_dbt_project_summary pipeline_artifacts/DE_pipeline_dbt_project_summary.csv dbt project-level features
pipeline_dlt pipeline_artifacts/DE_pipeline_dlt_features.csv dlt pipeline features
pipeline_files pipeline_artifacts/DE_pipeline_files.csv Discovered pipeline files
pipeline_kedro pipeline_artifacts/DE_pipeline_kedro_pipeline_features.csv Kedro pipeline features
pipeline_luigi pipeline_artifacts/DE_pipeline_luigi_task_features.csv Luigi task features
pipeline_prefect pipeline_artifacts/DE_pipeline_prefect_flow_features.csv Prefect flow features

The SQLite file DE_pipeline_artifacts.db is retained as a downloadable replication artifact and is not used by the Hugging Face Dataset Viewer.

Join Keys

  • full_name or repo_name (owner/repo) for repository-level and process tables.
  • repo_full_name for tables in pipeline_artifacts/.
  • (repo_full_name, file_path) links DE_pipeline_files.csv to the pipeline feature tables.

Loading Data from Hugging Face

Each table can be loaded independently using its configuration name:

from datasets import load_dataset

repos = load_dataset("taher-ghaleb/DEPosit", "repositories")
commits = load_dataset("taher-ghaleb/DEPosit", "commits")
issues = load_dataset("taher-ghaleb/DEPosit", "issues")
ci = load_dataset("taher-ghaleb/DEPosit", "ci_services")

To load pipeline feature tables:

from datasets import load_dataset

airflow = load_dataset("taher-ghaleb/DEPosit", "pipeline_airflow")
dbt = load_dataset("taher-ghaleb/DEPosit", "pipeline_dbt_model")
prefect = load_dataset("taher-ghaleb/DEPosit", "pipeline_prefect")

Each configuration represents one logical table with a consistent schema. The tables are intended to be joined for analysis using the keys described above.

Scripts (Scripts/)

Script Role
collect_github_repos_for_SE4DE_topics.py Topic-based repo discovery → Data/all_DE_repositories.csv
get_repo_commits_pr_issues_contributors_for_SE4DE_repos.py Commits, PRs, issues, contributors
get_issue_closers_for_SE4DE_repos.py Issue closer events
get_pr_reviews_graphql_for_SE4DE_repos.py PR reviews / merges (GraphQL)
get_pr_reviews_rest_for_SE4DE_repos.py PR reviews (REST alternative)
collect_github_repos_commits_per_ci_files.py Commits on CI-related paths
get_gha_workflow_runs_for_SE4DE_repos.py GitHub Actions run counts
compute_interactions_for_SE4DE_repos.py DE_repo_interactions.csv
compute_user_autonomy_for_SE4DE_repos.py DE_user_autonomy.csv
collect_pipeline_artifacts.py Discover and parse pipeline files
backfill_ci_gha_from_runs.py Add GitHub Actions to DE_ci_services.csv when runs exist but path detection missed them
github_api.py, github_tokens.py Shared API session and token loading
pipeline_parsers/ Framework-specific parsers
pipeline_schema.sql SQLite schema for pipeline collection

Quick start (analyze the shipped data) 

py -m pip install -r requirements.txt

Open Data/filtered_DE_repositories.csv and join to other Data/DE_*.csv files on full_name / repo_name.

GitHub authentication (re-collection only)

Do not commit personal access tokens. Scripts load credentials from (in order):

  1. --token / --tokens CLI flags (where supported)
  2. Environment variables: GITHUB_TOKEN_SE4DE (preferred) or GITHUB_TOKEN
  3. Optional local .env file — copy .env.example to .env and set your PAT
copy .env.example .env
# Edit .env and set GITHUB_TOKEN_SE4DE=<your-pat>

# Or set for the current shell only:
$env:GITHUB_TOKEN_SE4DE = "<your-pat>"

For heavy REST collection, rotate rate limits with comma-separated PATs:

$env:GITHUB_TOKENS = "<pat1>,<pat2>"

Example:

py Scripts/collect_pipeline_artifacts.py --token $env:GITHUB_TOKEN_SE4DE
py Scripts/get_gha_workflow_runs_for_SE4DE_repos.py --token $env:GITHUB_TOKEN_SE4DE

Typical collection order: topic discovery → development history → derived metrics → pipeline artifacts → optional backfill_ci_gha_from_runs.py.

Historical commit/PR text in Data/*.csv may contain third-party leaked tokens from upstream repos; these were redacted where detected. Re-run Scripts/redact_leaked_tokens_in_data.py after adding new CSV exports.
