sparkgrep 0.1.1a1

Pre-commit hooks for Apache Spark development (Databricks, EMR, Dataproc, and more)

SparkGrep

Pre-commit hook that detects debugging leftovers in Apache Spark applications.

🎯 Purpose

SparkGrep helps maintain clean Apache Spark codebases by detecting common debugging leftovers and performance anti-patterns that developers often forget to remove before committing code.

🔍 What it Detects

• display() calls - Jupyter/Databricks debugging function
• .show() methods - DataFrame inspection calls
• .collect() without assignment - Potential performance issues
• .count() without assignment - Unnecessary computations
• Custom patterns - User-defined patterns via configuration

🚀 Installation

pip install sparkgrep

📋 Usage

As a Pre-commit Hook

Add to your .pre-commit-config.yaml:

repos:
  - repo: https://github.com/leandroasaservice/sparkgrep
    rev: v0.1.1a1  # Use this preview version.
    hooks:
      - id: sparkgrep

Command Line

# Check specific files
sparkgrep src/my_script.py notebook.ipynb

# Check with additional patterns

# Disable default patterns and use only custom ones
sparkgrep --disable-default-patterns --additional-patterns "my_pattern:My description" src/
