How To Make a Web Crawler with Apache Nutch In February, 2024
Whether you are looking to obtain data from a website, track changes on the internet, or use a website API, website crawlers are a great way to get the data you need. While they have many components, crawlers fundamentally use a simple process: download the raw data, process and extract it, and, if desired, store the data in a file or database. There are many ways to do this, and many languages you can build your spider or crawler in.
Apache Nutch is a scalable web crawler built for easily implementing crawlers, spiders, and other programs to obtain data from websites. The project uses Apache Hadoop structures for massive scalability across many machines. Apache Nutch is also modular, designed to work with other Apache projects, including Apache Gora for data mapping, Apache Tika for parsing, and Apache Solr for searching and indexing data.
