Core documentation

dictConfig references

Dictionary schema details for version, formatters, handlers, loggers, and root.
logging.config.dictConfig function reference.

Prefer module loggers created with logging.getLogger(__name__).
Let applications configure handlers and formatters; libraries should emit logs without taking over routing.
Use basicConfig for simple scripts and dictConfig for centralized application configuration.
Explicitly set disable_existing_loggers: False in dictConfig unless disabling existing non-root loggers is intentional.
Use queue-based handlers when slow handlers would block async, threaded, or high-volume code paths.
