What is HP Vertica Architecture Type Like
What type of cluster architecture does Vertica promotes ?
Vertica uses the Shared Nothing Architecture(SN) in which each node is independent and self-sufficient, and there is no single point of contention across the system. More specifically, none of the nodes share memory or disk storage.
Shared Nothing Architecture system can scale almost infinitely simply by adding nodes in the form of inexpensive computers, since there is no single bottleneck to slow the system down.
It is stated that Shared Nothing Architectures certainly take longer to respond to queries that involve joins over large data sets from different machines. But with the help of Massively Parallel Processing (MPP) the parallel design leverages data projections to enable distributed storage and workload.
