Analytical Performance Modeling for Top-K Query Processing

  title={Analytical Performance Modeling for Top-K Query Processing},
  author={Hao Wu and Hui Fang},
Top-K query processing is one of the most important problems in large-scale Information Retrieval systems. Since query processing time varies for different queries, an accurate run-time performance prediction is critical for online query scheduling and load balancing, which could eventually reduce the query waiting time and improve the throughput.
