Advanced Scraping Techniques

Intelligent Rate Limiting

class AdaptiveRateLimiter:
    def __init__(self, initial_delay=1):
        self.delay = initial_delay
        self.success_count = 0
        self.fail_count = 0

    def adjust_delay(self, success):
        if success:
            self.success_count += 1
            if self.success_count > 100:
                self.delay = max(0.5, self.delay * .95)
        else:
            self.fail_count += 1
            self.delay *= 2

    async def wait(self):
        await asyncio.sleep(self.delay)

Distributed Scraping Architecture

class DistributedScraper:
    def __init__(self, worker_count=3):
        self.queue = asyncio.Queue()
        self.workers = []
        self.results = []

    async def worker(self, worker_id):
        while True:
            url = await self.queue.get()
            try:
                data = await self.scrape_url(url)
                self.results.append(data)
            finally:
                self.queue.task_done()

Advanced Proxy Management

class ProxyManager:
    def __init__(self):
        self.proxies = self.load_proxies()
        self.performance_metrics = {}

    def select_proxy(self):
        return weighted_choice(
            self.proxies,
            weights=[self.get_proxy_score(p) for p in self.proxies]
        )

    def get_proxy_score(self, proxy):
        metrics = self.performance_metrics.get(proxy, {})
        success_rate = metrics.get(‘success_rate‘, 0.5)
        speed = metrics.get(‘speed‘, 1.0)
        return success_rate * (1/speed)

Data Processing Pipeline

ETL Process

            ‘genres‘: self._parse_genres(raw_data[‘genres‘])
        }

    def transform(self, data):
        return pd.DataFrame(data).pipe(self._normalize_dates)
                                    .pipe(self._calculate_metrics)
                                    .pipe(self._enrich_data)

    def load(self, df):
        self.db_connection.bulk_insert(df)

Data Quality Assurance

class DataValidator:
    def validate_movie(self, movie_data):
        checks = [
            self._check_title_format(movie_data[‘title‘]),
            self._validate_year(movie_data[‘year‘]),
            self._verify_rating_range(movie_data[‘rating‘]),
            self._check_genre_consistency(movie_data[‘genres‘])
        ]
        return all(checks)
