Asynchronous web scraper

par RaulBlanko

Async web scraper works with the ElasticSearch cluster and MongoDB. It takes the list of organizations from MongoDB database and creates the bulk of tasks (coroutines) that run asynchronously. For every organization in the database, it crawls all the pages, clears the texts, and updates ES cluster with new text content. It saves all necessary things into draft ES index including sitemaps, visited pages, visiting reports, "robots.txt" rules.
