Abstract: Query processing in the shared-nothing parallel database systems demands a data exchange between processor nodes. In the paper, we present a theorem, which gives estimation for the amount of tuples which have to be transferred during processing partitioned relation. We consider the case when the transfer function is functionally dependent on an attribute, which is uniformly distributed relative to the partitioning attribute.
Keywords: parallel database system, shared-nothing architecture, partitioning parallelism, communication overhead.
