Communication Cost in Parallel Query Evaluation: A Tutorial
Summary: Defines the Massively Parallel Communication (MPC) model and analyzes communication for conjunctive-query evaluation on p servers using HyperCube/Shares and randomized hashing. Derives tight single-round bounds via the query hypergraph's fractional vertex cover (with skew extensions), discusses multi-round skew-handling and AGM connections; arbitrary-arity relations remain open.
