aqdlog 1.1.0

Asynchronous logging with queueing and deduplication

aqdlog (aqdlog)

Asynchronous logging helper for Python providing:

• Non-blocking logging via QueueHandler + QueueListener
• Simple deduplication of repeated (level, message) pairs
• Timestamp / level / function / line formatting
• Optional file output (console by default)

Installation

Using uv (recommended):

uv add aqdlog

Standard pip (after publishing):

pip install aqdlog

Quick Start

from aqdlog import log

logger = log("my_app", level="INFO")
logger.info("Service start")
logger.warning("Low disk space")
logger.warning("Low disk space")  # Duplicate suppressed

API

log(name: str, level: str = "INFO", log_file: str | None = None) -> logging.Logger

Args:

• name: Logger name (use name)
• level: Case-insensitive level name (INFO/DEBUG/WARNING/ERROR/CRITICAL)
• log_file: File path; omit for stderr

Returns a Logger configured with QueueHandler and a running QueueListener.

Deduplication

DuplicateFilter remembers (level, message) pairs; repeats are dropped for the lifetime of the logger instance. Structured extras are ignored.

Shutdown

Implementation currently assigns logger.shutdown = shutdown() (invoked immediately). Prefer logging.shutdown() on process exit to flush handlers.

Limitations

• Unlimited queue size (-1)
• Naive duplicate suppression
• Re-calling log() with same name returns existing logger; later level/file changes ignored

Roadmap

Configurable dedup strategy, max queue size, dynamic reconfiguration, graceful listener stop, structured logging.
