Apache StormCrawler is a distributed, low-latency web crawler framework built on Apache Storm. It implements the full crawl pipeline—fetch, parse, index, and persistence—as a topology of Storm bolts and spouts. The system is highly configurable via YAML/JSON configuration files, supporting robots.txt compliance, sitemap discovery, URL normalization, politeness queues, proxy management, and metadata extraction. Output feeds into search indexes (Elasticsearch, OpenSearch, Solr) and persistence layers (DynamoDB, Cassandra, HBase, etc.). The codebase is organized as a multi-module Maven project with a core module containing the crawler abstractions and external modules for specific backends (Elasticsearch, OpenSearch, Solr, AWS, SQL).
