Massively parallel processing (MPP :
In MPP database systems, each node has its own memory, processor, and
disk. It is known as a share nothing architecture. An MPP database system is more powerful than systems with shared disks because data loading is happening in parallel across multiple nodes that have their own disks.
The main advantage of MPP database systems is that the performance increase is linear
ex:
In MPP database systems, if you put in ten nodes, the performance is
almost ten times the performance of a single node.
