## What it is
Redis-based components for Scrapy that enable distributed crawling and scraping by sharing a Redis queue across multiple spider instances. It provides plug-and-play Scrapy components including a scheduler with duplication filter, item pipeline, and base spiders.

## Use cases
- run distributed crawls across multiple spider instances sharing one queue
- scale broad multi-domain web scraping with multiple workers
- push scraped items to a Redis queue for distributed post-processing
- deduplicate URLs across distributed Scrapy spiders
- pass JSON metadata with URLs through a Redis-backed request queue

## When to choose
- you already use Scrapy and need to distribute crawling across machines
- you want plug-and-play Redis-backed scheduler and pipeline components
- you need multiple workers sharing a single crawl queue

## When to avoid
- you need advanced features like URL expiration or prioritization (consider Frontera)
- you run a single-machine crawl with no need for distribution
- you don't use Scrapy as your crawling framework

## Facets
- artifact type: library
- maturity: active
- function: web-scraping, message-queue, caching, middleware
- domain: crawlers, web-development, databases, developer-tools
- platform: python, cross-platform
- tags: scrapy, redis, distributed-crawling, spider, crawler
