# Partitioning data Partitioning data allows you to distribute all the data from a set into distinct subsets according to the rule applied on a table or row, where these subsets form a partition of the original set with no item replicated into multiple groups. Partitioning data is an important feature for scaling up and scaling out your [Pentaho Data Integration](broken://pages/NFVy2hHNhAuL8w6d6iX8) transformations and jobs. Scaling up makes the most of a single server with multiple CPU cores, while scaling out maximizes the resources of multiple servers operating in parallel. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
