Communication Steps for Parallel Query Processing
Summary: Tight single-round communication-space tradeoff for MPC: any 1-round algorithm needs replication exponent ε ≥ 1 - 1/τ*, where τ* is the fractional vertex cover of query q, with matching algorithms for certain database instances. First multi-round lower bounds under tuple-based routing, yielding a rounds-vs-ε tradeoff for tree-like conjunctive queries and implying transitive-closure cannot be done in O(1) rounds.
