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: Python AsyncIO Web Scraper with Exponential Backoff & SQLite Sink
This module implements a production-ready web scraper using Python's asyncio library.
It features bounded concurrency, exponential backoff with jitter, and a SQLite sink for storing scraped data.
The module is designed to be used from the command line, with configuration options specified via typed dataclasses.
Usage:
python web_scraper.py --url https://example.com --concurrency 10 --db_path ./scraped_data.db
The module will scrape the specified URL, storing the HTML response in the SQLite database.
In the event of a failure, the module will employ exponential backoff with jitter to retry the request.
Configuration:
- url: The URL to scrape
- concurrency: The maximum number of concurrent requests
- db_path: The path to the SQLite database file
Error Handling:
- The module will log errors using the structlog library, with a JSON formatter for easy parsing
- Errors will be handled deterministically, with the module retrying failed requests using exponential backoff
