Threshold Values for Processing Distributed Queries [PDF]
The Computer Journal, 1991 A strategy to process a distributed query is formed using estimates of intermediate result sizes and delays due to network data transfer and CPU processing. Strategy execution is monitored, and corrected if observed parameter values differ substantially from their estimates.
