BUbiNG: Massive Crawling for the Masses / P. Boldi, A. Marino, M. Santini, S. Vigna. - In: ACM TRANSACTIONS ON THE WEB. - ISSN 1559-1131. - 12:2(2018 Jun 02), pp. 12.12:1-12.12:26. [10.1145/3160017]
Abstract:
Although web crawlers have been around for twenty years by now, there is virtually no freely available,
open-source crawling software that guarantees high throughput, overcomes the limits of single-machine
systems, and, at the same time, scales linearly with the amount of resources available. This article aims at
filling this gap, through the description of BUbiNG, our next-generation web crawler built upon the authors’
experience with UbiCrawler [9] and on the last ten years of research on the topic. BUbiNG is an open-source
Java fully distributed crawler; a single BUbiNG agent, using sizeable hardware, can crawl several thousand
pages per second respecting strict politeness constraints, both host- and IP-based. Unlike existing open-source
distributed crawlers that rely on batch techniques (like MapReduce), BUbiNG job distribution is based on
modern high-speed protocols to achieve very high throughput.
