Massively Parallel Processing (MPP)

An architecture that splits data and query work across many nodes that process their portions in parallel.

Definition

MPP engines such as Redshift, Synapse dedicated SQL pools, BigQuery, Teradata and Snowflake's warehouses scale analytic queries by distributing rows. Data distribution and skew strongly affect performance in classic MPP systems.

Exam tip

Snowflake is described as a hybrid: shared-disk central storage with MPP compute clusters.
