Shared-Nothing Architecture

A distributed design in which each node has its own CPU, memory and disk, sharing nothing with other nodes.

Definition

Shared-nothing scales well but requires data to be redistributed when nodes are added. Snowflake combines a shared-disk central data store with shared-nothing MPP compute clusters.

Exam tip

SnowPro Core describes Snowflake as a hybrid of shared-disk and shared-nothing architectures.
