UbiCrawler: a scalable fully distributed Web crawler

  title={UbiCrawler: a scalable fully distributed Web crawler},
  author={Paolo Boldi and Bruno Codenotti and Massimo Santini and Sebastiano Vigna},
  journal={Software: Practice and Experience},
We report our experience in implementing UbiCrawler, a scalable distributed Web crawler, using the Java programming language. The main features of UbiCrawler are platform independence, linear scalability, graceful degradation in the presence of faults, a very effective assignment function (based on consistent hashing) for partitioning the domain to crawl, and more in general the complete decentralization of every task. The necessity of handling very large sets of data has highlighted some…
