Status This project is an early-alpha. There are some incomplete features (see Issues).
Picologging is a high-performance logging library for Python. picologging is 4-10x faster than the logging
module in the standard library.
Picologging is designed to be used as a drop-in replacement for applications which already use logging, and supports the same API as the logging
module.
$ pip install picologging
Import picologging as logging
to use picologging instead of the standard library logging module.
This patches all the loggers registered to use picologging loggers and formatters.
import picologging as logging
logging.basicSetup()
logger = logging.getLogger()
logger.info("A log message!")
logger.warning("A log message with %s", "arguments")
