+# Use environment variable to switch backends +artifact_uri = os.getenv( + "ARTIFACT_URI", + "file:///tmp/artifacts" # Default to local +) + +artifact_store = create_artifact_store(artifact_uri) +``` + +**Usage:** + +```bash +# Development +python train.py + +# Production +export ARTIFACT_URI="s3://prod-models/astroml" +python train.py +``` + +### Pattern 2: Multi-Experiment Tracking + +```python

managing, computing, storing, and retrieving features for machine learning workflows. + +## Overview + +The Feature Store is designed to solve common challenges in machine learning feature engineering: + +- **Feature Reuse**: Avoid recomputing the same features multiple times +- **Consistency**: Ensure features are computed consistently across training and inference +- **Versioning**: Track feature definitions and computations over time +- **Discovery**: Make features discoverable and well-documented +- **Performance**: Cache and optimize feature storage for fast access +- **Lineage**: Track feature dependencies and data provenance + +## Architecture + +The Feature Store consists of several key components: + +### Core Components + +1. **FeatureStore** - Main interface for feature management +2. **FeatureRegistry** - Registry of available feature computers +3. **FeatureStorage** - Storage backend for feature values and metadata +4. **FeatureEngine** - Computation engine for parallel feature processing +5. **FeatureTransformers** - Feature preprocessing and transformation utilities +6. **FeatureCache** - Multi-level caching system +7. **FeatureVersionManager** - Versioning and metadata management + +### Data Models + +- **FeatureDefinition** - Feature metadata and computation specification +- **FeatureValue** - Computed feature values with timestamps +- **FeatureSet** - Collections of related features +- **FeatureVersion** - Version information for features +- **FeatureLineage** - Dependency tracking between features + +## Quick Start + +### Basic Usage + +```python +from astroml.features import create_feature_store +import pandas as pd + +# Create feature store +store = create_feature_store("./my_feature_store") + +# Load transaction data

+```python +# Compute frequency features +frequency_features = store.compute_and_store( + feature_name="daily_transaction_count", + data=data, + entity_col="entity_id", + timestamp_col="timestamp", +) + +# Compute structural features +structural_features = store.compute_and_store( + feature_name="degree_centrality", + data=data, + entity_col="entity_id", + timestamp_col="timestamp", +) + +# Create

settings +optimizer.save_dataframe(optimized_data, "account_balance.parquet") +``` + +### Batch Processing + +```python +# Use batch mode for better performance +with store.batch_mode(): + # Store multiple features + for feature_name in feature_names: + values = compute_feature(feature_name, data) + store.store_feature(feature_name, values) + + # Cache is automatically cleared at the end +``` + +### Parallel Computation + +```python +# Configure computation engine for parallel processing +from astroml.features.feature_engine import create_computation_engine + +engine = create_computation_engine(max_workers=8) + +# Process features in parallel +results = engine.compute_features_batch( + feature_configs=feature_configs, + data=data, + parallel=True, +) +``` + +## Monitoring and Debugging + +### Feature Discovery + +```python +# List all available features +features = store.list_features() +for feature in features: + print(f"{feature.name}: {feature.description}") + print(f" Type: {feature.feature_type.value}") + print(f" Tags: {', '.join(feature.tags)}") + print(f" Owner: {feature.owner}") + print(f" Status: {feature.status.value}") +

existence +feature_def = store.storage.get_feature_definition("feature_name_v1") +if feature_def is None: + print("Feature not found") +``` + +## Best Practices + +### Feature Design + +1. **Descriptive Names**: Use clear, descriptive feature names +2. **Documentation**: Provide comprehensive descriptions +3. **Type Safety**: Specify correct feature types +4. **Tagging**: Use consistent tags for categorization +5. **Parameters**: Make features configurable through parameters + +### Performance + +1. **Caching**: Enable appropriate caching strategies +2. **Batch Operations**: Use batch mode for multiple operations +3. **Parallel Processing**: Enable parallel computation for independent features +4. **Storage Optimization**: Use optimal storage formats +5. **Indexing**: Properly index data for fast retrieval + +### Version Management + +1. **Semantic Versioning**: Use meaningful version numbers +2. **Change Tracking**: Document all changes thoroughly +3. **Approval Process**: Use status transitions for deployment +4. **Backward Compatibility**: Maintain compatibility when possible +5. **Deprecation**: Properly deprecate old versions + +### Data Quality + +1. **Validation**: Validate input data before computation +2. **Error Handling**: Handle edge cases gracefully +3. **Logging**: Log important events and errors +4. **Testing**: Test features thoroughly +5. **Monitoring**: Monitor feature quality over time + +## Integration Examples + +### Machine Learning Pipeline + +```python +# Feature store for ML pipeline +class MLPipeline: + def __init__(self):

FeatureServer() +features = server.get_features("account123", ["balance", "frequency"]) +``` + +## Troubleshooting + +### Common Issues + +1. **Feature Not Found**: Check if feature is registered and spelled correctly +2. **Memory Issues**: Reduce cache size or use disk caching +3. **Performance**: Enable parallel processing and optimize storage +4. **Version Conflicts**: Check feature version
