We engineered this zero-bloat Python 3.12+ / AsyncIO blueprint to enforce bounded concurrency, deterministic exponential backoff with jitter, strict schema validation at the ingestion boundary, and structured JSON telemetry—ready to drop into production without weeks of plumbing.

AI Dev Tool: Zero-Dependency Distributed Lock & Queue Worker on SQLite WAL.
This module implements a distributed lock and queue worker using SQLite WAL mode.
It provides a zero-dependency solution for concurrent task execution with bounded concurrency.
The architecture consists of a SQLite database with a lock table and a queue table.
The lock table is used to manage concurrent access to the queue, while the queue table stores tasks to be executed.
The module uses exponential backoff with jitter for retrying failed tasks and structured JSON logging for monitoring.
It also provides deterministic error handling to ensure that tasks are executed reliably.
To use this module, run the following command:
python -m ai_dev_tool --db-path /path/to/db.sqlite --concurrency 5 --task-count 100
This will execute 100 tasks with a concurrency of 5, using the SQLite database at /path/to/db.sqlite.
Configuration:
--db-path: Path to the SQLite database file
--concurrency: Maximum number of concurrent tasks
--task-count: Number of tasks to execute
Usage:
python -m ai_dev_tool --help
