Big Data Publication Fast Data in the Era of Big Data: Twitter’s Real-Time Related Query Suggestion Architecture Architecture behind Twitter's real-time related query suggestion and spelling correction service – First implementation: typical Hadoop-based analytics stack, did not meet the latency requirement – Second implementation: system deployed in production, custom in-memory processing engine

Big Data Publication Fast Candidate Generation for Two-Phase Document Ranking: Postings List Intersection with Bloom Filters M2012.pdf M2012.pdf Most modern web search engines employ a two-phase ranking strategy: a candidate list of documents is generated using a “cheap” but low-quality scoring function, which is then reranked by an “expensive" but high-quality method Candidate generation for conjunctive query processing in this context A fast, approximate postings list intersection algorithms based on Bloom Filters
