Installation

pip install -r requirements.txt

Quick Start

  1. Add your Spark code to optimize in input/spark_code_input.py

  2. Start the MCP server:

python v1/run_server.py

  1. Run the client to optimize your code:

python v1/run_client.py

This will generate two files:

  • output/optimized_spark_example.py: The optimized Spark code with detailed optimization comments

  • output/performance_analysis.md: Comprehensive performance analysis

  1. Run and compare code versions:

python v1/run_optimized.py

This will:

  • Execute both original and optimized code

  • Compare execution times and results

  • Update the performance analysis with execution metrics

  • Show detailed performance improvement statistics

Why MCP?

The Model Context Protocol (MCP) provides several key advantages for Spark code optimization:

Direct Claude AI Call vs MCP Server

Aspect

Direct Claude AI Call

MCP Server

Integration

• Custom integration per team

• Manual response handling

• Duplicate implementations

• Comprehensive improvements

Validation

• Manual testing required

• No performance metrics

• Uncertain outcomes

• Automated testing

• Performance metrics

• Validated results

Workflow

• Ad-hoc process

• No validation

• Complex maintenance

MCP

@register_tool("optimize_spark_code")

async def optimize_spark_code(code: str):

• Auto-discovery

• Type checking

• Easy extension

3. Resource Management

Approach

Code Example

Benefits

Traditional

def __init__(self):

  self.claude = init_claude()

  self.spark = init_spark()

• Manual orchestration

• Manual cleanup

• Error-prone

MCP

@requires_resources(["claude_ai", "spark"])

async def optimize_spark_code(code: str):

• Auto-coordination

• Lifecycle management

• Error handling

4. Communication Protocol

Approach

Code Example

Benefits

Traditional

{"type": "request",

 "payload": {"code": code}}

• Custom format

• Manual validation

• Custom debugging

MCP

{"method": "tools/call",

 "params": {"name": "optimize_code"}}

• Standard format

• Auto-validation

• Easy debugging

Features

  • Intelligent Code Optimization: Leverages Claude AI to analyze and optimize PySpark code

  • Performance Analysis: Provides detailed analysis of performance differences between original and optimized code

  • MCP Architecture: Implements the Model Context Protocol for standardized AI model interactions

  • Easy Integration: Simple client interface for code optimization requests

  • Code Generation: Automatically saves optimized code to separate files

Advanced Usage

You can also use the client programmatically:

from spark_mcp.client import SparkMCPClient

async def main():
    # Connect to the MCP server
    client = SparkMCPClient()
    await client.connect()

    # Your Spark code to optimize
    spark_code = '''
    # Your PySpark code here
    '''

    # Get optimized code with performance analysis
    optimized_code = await client.optimize_spark_code(
        code=spark_code,
        optimization_level="advanced",
        save_to_file=True  # Save to output/optimized_spark_example.py
    )
    
    # Analyze performance differences
    analysis = await client.analyze_performance(
        original_code=spark_code,
        optimized_code=optimized_code,
        save_to_file=True  # Save to output/performance_analysis.md
    )
    
    # Run both versions and compare
    # You can use the run_optimized.py script or implement your own comparison
    
    await client.close()
    
    # Analyze performance
    performance = await client.analyze_performance(spark_code, optimized_code)

    await client.close()

# Join and analyze
result = emp_df.join(dept_df, "dept") \
    .groupBy("dept", "location") \
    .agg({"salary": "avg", "age": "avg", "id": "count"}) \
    .orderBy("dept")

  1. Optimized Code (output/optimized_spark_example.py):

# Performance-optimized version with caching and improved configurations

    .appName("EmployeeAnalysis") \
    .config("spark.sql.shuffle.partitions", 200) \
    .getOrCreate()

# Create and cache DataFrames
emp_df = spark.createDataFrame(employees, ["id", "name", "age", "dept", "salary"]).cache()
dept_df = spark.createDataFrame(departments, ["dept", "location", "budget"]).cache()

# Optimized join and analysis

    .groupBy("dept", "location") \
    .agg(
        avg("salary").alias("avg_salary"),
