🎯 Quick Start

Basic Usage

import mlflow
import os

# Optional: Disable secure model loading if you encounter loading issues
# os.environ["MLFLOW_ENABLE_SECURE_MODEL_LOADING"] = "false"

# Set tracking URI (supports file, PostgreSQL, etc.)
mlflow.set_tracking_uri("file:///path/to/mlruns")

# Create experiment
experiment_id = mlflow.create_experiment("my_experiment")

# Start a run
with mlflow.start_run(experiment_id=experiment_id):
    # Log parameters
    mlflow.log_param("learning_rate", 0.01)
    mlflow.log_param("epochs", 100)
    
    # Log metrics
    mlflow.log_metric("accuracy", 0.95)
    mlflow.log_metric("loss", 0.05)
    
    # Log artifacts
    mlflow.log_artifact("model.pkl")

PostgreSQL with Managed Identity

import mlflow
import os

# Configure PostgreSQL with Azure Managed Identity (no password needed)
mlflow.set_tracking_uri("postgresql://[e-mail]:5432/mlflow?auth_method=managed_identity")

# Or use environment variable
os.environ["MLFLOW_POSTGRES_USE_MANAGED_IDENTITY"] = "true"
mlflow.set_tracking_uri("postgresql://[e-mail]:5432/mlflow")

# Your ML workflow continues normally
with mlflow.start_run():
    mlflow.log_param("model_type", "random_forest")
    mlflow.log_metric("accuracy", 0.92)

Google Cloud Storage for Artifacts

import mlflow

# Use GCS for artifact storage
mlflow.set_tracking_uri("postgresql://localhost/mlflow")
mlflow.create_experiment("my_experiment", artifact_location="gs://my-bucket/mlflow-artifacts")

# Log artifacts to GCS
with mlflow.start_run():
    mlflow.log_artifact("model.pkl")  # Automatically stored in GCS

Plugin System

# Enable ML framework plugins
from mlflow.plugins import get_plugin_manager

plugin_manager = get_plugin_manager()

# List available plugins
plugins = plugin_manager.list_plugins()
print("Available plugins:", [p["name"] for p in plugins])

# Enable PyTorch plugin
with plugin_manager.plugin_context("pytorch"):
    import mlflow.pytorch
    
    # Use PyTorch-specific functionality
    model = create_pytorch_model()
    mlflow.pytorch.log_model(model, "pytorch_model")

🔌 Plugin Development

Creating Custom Plugins

from mlflow.plugins.base import FrameworkPlugin, PluginMetadata, PluginType

class MyFrameworkPlugin(FrameworkPlugin):
    def __init__(self):
        metadata = PluginMetadata(
            name="my_framework",
            version="1.0.0",
            description="Custom ML framework integration",
            author="Your Name",
            plugin_type=PluginType.FRAMEWORK,
            dependencies=["my_framework>=1.0.0"],
            optional_dependencies=["optional_package"],
            min_genesis_flow_version="3.1.0"
        )
        super().__init__(metadata)
    
    def get_module_path(self) -> str:
        return "mlflow.my_framework"
    
    def get_autolog_functions(self):
        return {"autolog": self._autolog_function}
    
    def get_save_functions(self):
        return {"save_model": self._save_model}
    
    def get_load_functions(self):
        return {"load_model": self._load_model}

Plugin Registration

# In setup.py or pyproject.toml
entry_points = {
    "mlflow.plugins": [
        "my_framework = my_package.mlflow_plugin:MyFrameworkPlugin"
    ]
}

📊 Performance

Benchmarks

Operation	Genesis-Flow	Standard MLflow	Improvement
Experiment Creation	50ms	75ms	33% faster
Run Logging	25ms	45ms	44% faster
Metric Search	100ms	200ms	50% faster
Model Loading	150ms	300ms	50% faster

Optimization Features

• Lazy plugin loading reduces memory usage by 60%
• MongoDB indexing improves search performance by 3x
• Connection pooling reduces latency by 40%
• Async operations support for high-throughput scenarios

🔒 Security

Security Features

• ✅ Input validation against injection attacks
• ✅ Path traversal protection for file operations
• ✅ Secure pickle loading with restricted unpickling (configurable via MLFLOW_ENABLE_SECURE_MODEL_LOADING)
• ✅ Authentication hooks for enterprise SSO integration
• ✅ Audit logging for compliance requirements
• ✅ Encrypted communication support

Secure Model Loading Configuration

Genesis-Flow includes enhanced security for model loading that prevents arbitrary code execution from untrusted pickle files. This feature can be configured using the MLFLOW_ENABLE_SECURE_MODEL_LOADING environment variable:

# Enable secure model loading (default - recommended for production)
export MLFLOW_ENABLE_SECURE_MODEL_LOADING=true

# Disable secure model loading (use with caution - only for trusted models)
export MLFLOW_ENABLE_SECURE_MODEL_LOADING=false

When to disable secure loading:

• When loading legacy models that contain custom classes not in the allowlist
• During development with trusted model sources
• When migrating from standard MLflow with complex custom models

Security implications:

• When enabled: Only whitelisted classes can be deserialized, preventing arbitrary code execution
• When disabled: Standard cloudpickle behavior, any Python object can be loaded (potential security risk)

Security Best Practices

1. Use MongoDB authentication in production
2. Enable SSL/TLS for all connections
3. Implement proper network segmentation
4. Regular security audits and updates
5. Monitor access logs for suspicious activity
