Abstract
Partial replication is one type of optimization to speed
up execution of queries submitted to large datasets. In
partial replication, a portion of the dataset is extracted,
re-organized, and re-distributed across the storage system.
The objective is to reduce the volume of I/O and increase
I/O parallelism for different types of queries and for the
