Commercial parallel database systems such as DB2 Parallel Edition (DB2 PE) [1,2] are delivering the ability to execute complex queries on very large databases. However, the serial application interface to these database systems can become a bottleneck for a growing list of applications such as mailing list generation and data propagation from a warehouse to smaller data marts. In this abstract, we describe the CURRENT NODE and NODENUMBER functions provided by DB2 PE and show how these two functions can be used to retrieve data in parallel in a linearly scalable manner with respect to the number of nodes in the system.
