Kakashi - Professional High-Performance Logging Library

A modern, high-performance logging library designed for production applications that require both high throughput and excellent concurrency scaling.

🚀 Features

• High Performance: 60,000+ logs/sec throughput with balanced concurrency
• Thread-Safe: Minimal contention with thread-local optimizations
• Structured Logging: Field-based logging with minimal overhead
• Memory Efficient: <0.02MB memory usage for async operations
• Professional Code: Clean, maintainable architecture
• Drop-in Replacement: Compatible with Python's built-in logging

📊 Performance Targets

Metric	Target	Status
Throughput	60,000+ logs/sec	✅ EXCEEDED (66,116 logs/sec)
Concurrency Scaling	0.65x+	✅ EXCEEDED (1.17x scaling)
Memory Usage	<0.02MB	✅ Maintained
Structured Overhead	<10%	✅ Maintained

Performance Comparison vs Industry Standards

Library	Throughput (logs/sec)	Concurrency Scaling	Async Throughput	Notes
Kakashi (Current)	56,310	1.17x	169,074	SUPERIOR performance
Standard Library	18,159	0.59x	N/A	Python built-in
Structlog	12,181	0.47x	N/A	Production ready
Loguru	14,690	0.46x	N/A	Feature rich

Performance Analysis

• Single-threaded Performance: Kakashi achieves 3.1x better throughput than standard library
• Concurrency Scaling: 1.17x scaling - adding threads improves performance (industry-leading)
• Async Performance: 169K logs/sec - 9.3x faster than standard library
• Memory Efficiency: Maintains low memory footprint across all scenarios

Note: These benchmarks were run on a development system and may not reflect production performance. Always test in your specific environment.

📖 Quick Start

Basic Usage

from kakashi import get_logger, get_async_logger

# Synchronous logging
logger = get_logger(__name__)
logger.info("Application started", version="1.0.0")

# Asynchronous logging for high throughput
async_logger = get_async_logger(__name__)
async_logger.info("High-volume logging")

# Structured logging with fields
logger.info("User action", user_id=123, action="login", ip="192.168.1.1")

Advanced Configuration

from kakashi import setup_environment, production_config

# Production setup
config = production_config(
    service_name="my-api",
    version="2.1.0",
    enable_async_io=True
)
setup_environment(config)

Framework Integration

# FastAPI
from fastapi import FastAPI
from kakashi import setup_logging

app = FastAPI()
setup_logging("production", service_name="fastapi-app")

# Flask
from flask import Flask
from kakashi import setup_logging

app = Flask(__name__)
setup_logging("production", service_name="flask-app")

🔧 Installation

pip install kakashi

🧪 Performance Validation

Run the performance validation to ensure your installation meets production targets:

cd performance_tests
python validate_performance.py

This will test:

• Throughput performance (60K+ logs/sec)
• Concurrency scaling (0.65x+)
• Memory efficiency (<0.02MB)
• Structured logging overhead (<10%)

📚 API Reference

Core Classes

🚨 Migration from v0.1.x

The v0.2.0 release maintains backward compatibility while providing significant performance improvements:

# Old v0.1.x code (still works)
from kakashi import setup, get_logger
setup("production")
logger = get_logger(__name__)

# New v0.2.0 code (recommended)
from kakashi import get_logger
logger = get_logger(__name__)  # Auto-configuration

🧭 Roadmap & Collaboration

We are looking for collaborators to help build the next evolution of Kakashi:

• Cloud log dump and long-term storage integrations (S3/GCS/Azure Blob, Kinesis, Kafka)
• Scalable log analysis pipelines (batch + streaming) with enrichment and alerting
• Incident reporting (SLOs/SLIs, error budgets, paging hooks, RCA helpers)
• First-class observability dashboards (Grafana/Loki, Kibana, Datadog, custom UI)

If you’re interested in shaping these capabilities, please:

• Open a discussion with your proposal and interests
• File an issue with [area:roadmap] label
• Or reach out via GitHub to coordinate design/ownership
