Scrapy Redis

Scrapy-Redis is a practical, battle-tested extension that adds Redis-based components to Scrapy for building distributed web crawling systems.

Key Features:

• Distributed Queue - Share request queues across multiple Scrapy spiders via Redis
• Deduplication - Redis-based request fingerprinting prevents duplicate crawls
• Shared Scheduler - Coordinate multiple crawler instances with a centralized scheduler
• Item Pipeline - Push scraped items to Redis for downstream processing
• Drop-In - Minimal configuration changes to distribute existing Scrapy spiders

Whether you're scaling Scrapy crawlers across multiple servers, building real-time scraping pipelines, or coordinating distributed extraction, Scrapy-Redis provides the essential components for distributed Scrapy deployments.
