AI Dev Tool: Python AsyncIO Web Scraper with Exponential Backoff & SQLite Sink

1. The Production Bottleneck

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, asynchronous web scraper with exponential backoff and SQLite sink.
It utilizes bounded concurrency to prevent overwhelming the target web servers and ensures robust error handling.

The module's architecture consists of the following components:
- WebScraper: responsible for scraping web pages asynchronously
- ExponentialBackoff: implements exponential backoff with jitter for handling temporary failures
- SQLiteSink: stores scraped data in a SQLite database
- CLI: provides a command-line interface for configuring and running the web scraper

To use this module, run it from the command line and provide the following arguments:
- --url: the URL of the web page to scrape
- --db: the path to the SQLite database file
- --max-concurrency: the maximum number of concurrent requests (default: 10)
- --max-retries: the maximum number of retries for failed requests (default: 3)

Example usage:
python web_scraper.py --url https://example.com --db example.db --max-concurrency 5 --max-retries 2
