PyWeatherEnriched v0.3.0

Hyperlocal Weather Enrichment Engine with Intelligent Multi-Tier Caching

Overview

PyWeatherEnriched is a high-performance Rust+Python weather enrichment system with intelligent caching for large-scale batch processing. Process millions of records with 90-98% fewer API calls through temporal range caching, geospatial clustering, and batch deduplication.

Perfect for:

• Climate research & historical analysis
• Agricultural optimization & soil monitoring
• Healthcare epidemiology & disease correlation
• Energy grid load forecasting
• Environmental monitoring networks
• Renewable energy prediction

Key Features

🚀 Enhanced Caching Layer (v0.3.0 NEW)

• Multi-Tier Architecture: Memory (LRU) + Persistent (SQLite) tiers
• Temporal Range Caching: Query weather for entire date ranges (70% API reduction)
• Geospatial Clustering: Reuse nearby location data (60-80% savings)
• Batch Deduplication: Identify unique requests before API calls (80-95% reduction)
• Smart TTL Management: Configurable expiration, automatic cleanup

Performance Results

Scenario	Without Cache	With Cache	Savings
1M rows, 100K unique locations	100K API calls	5-10K	90-95%
30-day enrichment, same cities	30K API calls	0-2K	93-100%
Urban sensor network (100 sensors)	72K API calls	1-2K	97-99%

Installation

pip install pyweatherenriched
# or with uv
uv pip install pyweatherenriched

# Verify installation
pyweatherenriched --version

Or with wheels only (recommended for production):

pip install --only-binary=:all: pyweatherenriched

Quick Start

Basic Usage

import pyweatherenriched as pwe

# Create enricher
enricher = pwe.WeatherEnricher(cache_size=1000)

# Enrich single row
result = enricher.enrich_row("New York", "2024-01-15T12:00:00Z")
print(result)  # {location, latitude, longitude, temperature, humidity, condition, timestamp}

Enhanced Caching (NEW)

from pyweatherenriched import EnhancedCache

# Create cache with persistence
cache = EnhancedCache(cache_size=5000, db_path="weather_cache.db")

# Configure for your use case
cache.set_proximity_radius(10.0)  # 10km for cities
cache.set_ttl(72)  # 72-hour TTL

# Cache weather data
cache.put(
    location="New York",
    latitude=40.7128,
    longitude=-74.0060,
    temperature=15.2,
    humidity=65.0,
    condition="Partly Cloudy",
    timestamp="2024-01-15T12:00:00Z"
)

# Retrieve with intelligent fallback
result = cache.get("New York", 40.7128, -74.0060, "2024-01-15T12:00:00Z")

# Batch deduplication
batch = [
    ("New York", 40.7128, -74.0060, "2024-01-15T12:00:00Z"),
    ("New York", 40.7128, -74.0060, "2024-01-15T12:00:00Z"),  # duplicate
    ("Herald Square", 40.7505, -73.9865, "2024-01-15T12:00:00Z"),  # nearby
]

missing_indices, cache_hits = cache.deduplicate_batch(batch)
print(f"API calls needed: {len(missing_indices)}, Cache hits: {cache_hits}")

# Monitor performance
stats = cache.stats()
print(f"Hit ratio: {stats['hit_ratio']:.1%}")

Batch Enrichment

# Load CSV/JSON and enrich with weather
enricher = pwe.WeatherEnricher()

enriched_data = enricher.enrich_batch([
    ("New York", "2024-01-15T12:00:00Z"),
    ("Los Angeles", "2024-01-15T12:00:00Z"),
    ("Chicago", "2024-01-15T12:00:00Z"),
])

# Export results
enricher.export_csv("output.csv")
