Evaluation dynamic processing of distributed queries
Peter Bodorik, J. S. Riordon · 2003
Several issues that arise in processing distributed queries dynamically are investigated. The effect of inaccuracies in estimation on the cost/delay of strategies is considered. Two methods than can be used to decide whether or not to correct a strategy are examined and compared. The problem of aborting operations in process is also examined, i.e. whether operations which are in progress should be aborted or whether they should be permitted to complete.>
