what is data slice
Manage data slices. A data slice is a logical representation of the data that is saved in the partitions of a disk. The data slice contains pieces of each user database and table. The IBMÂ® NetezzaÂ® system distributes the user data to all of the disks in the system by using a hashing algorithm. Each data slice has an ID, and is logically owned by a SPU to process queries on the data that is contained within that data slice.
