Ten Thousand SQLs: Parallel Keyword Queries Computing

Summary: Keyword queries in RDBMS are implemented as thousands of SQLs (CNs); this work explores multicore parallelization of CN generation and CN evaluation. Proposes three approaches: query-level SQL distribution, operation-level cost re-estimation, and adaptive partitioning to reduce partitioning cost and skew; tested on DBLP and IMDB.
