lo3 0.3.0a1

Faster logger than python native logging package.

Lo3: High-Performance Python Logging with Rust (Alpha Version)

Overview

Lo3 is an extremely fast, Rust-based logging solution for Python applications. It provides a simple Python interface while leveraging Rust's performance to deliver logging capabilities up to 80 times faster than Python's native logging module in high-volume scenarios.

Please Note: This is an alpha version with limited features. Currently, RustPyLogger only supports logging to files. Additional features are in active development.

Current Features

• High-performance logging to files (up to 80x faster than Python's native logging)
• Python-friendly API with familiar log levels (debug, info, warning, error)
• Thread-safe operations
• Efficient handling of high-volume logs
• Support for additional context (kwargs) in log messages
• Minimal CPU and memory overhead

Planned Features (In Development)

• Support for all handlers provided in logging
• Structured logging support
• Asynchronous logging
• Log rotation and archiving
• Configurable log formatting

Installation

• via pypi:

  pip install lo3
  

Usage

Here's a simple example of how to use Lo3 in its current alpha state:

from lo3 import RustLogger

# Initialize the logger (currently only supports file logging)
logger = RustLogger("app.log")

# Log messages at different levels
logger.debug("This is a debug message", {"extra": "info"})
logger.info("This is an info message")
logger.warning("This is a warning")
logger.error("This is an error", {"error_code": 500})

# Ensure all logs are written
logger.flush()

Performance

In our benchmarks, Lo3 showed significant performance improvements over Python's native logging module:

• Test: Writing 1,000,000 log messages (250,000 each of debug, info, warning, and error) to a file
• Lo3: ~101.39 seconds
• Python's logging module: ~522.20 seconds

This represents an 80x speedup in this high-volume logging scenario.

Benchmarking

To run the benchmarks yourself:

1. clone https://github.com/DataEnggNerd/MH370
2. Run the provided tests script:

   python tests/test-lo3.py
   python tests/test-logging.py
   

Contributing

As this is an alpha version, we welcome contributions, especially for the features currently in development. Please feel free to submit pull requests, create issues, or suggest new features.

Limitations

• Currently only supports logging to files
• No support yet for log rotation or size limits
• Configuration options are limited in this alpha version
