Greenplum

About Greenplum

An advanced, fully featured, open source data warehouse based on PostgreSQL. Greenplum provides powerful and rapid analytics on petabyte-scale data volumes with massively parallel processing (MPP) architecture.

Key Features

• 1Massively parallel PostgreSQL-based analytical database
• 2Append-optimized column tables for analytical workload compression
• 3PL/Python and PL/R UDFs run Python and R code in-database
• 4gpfdist parallel data loading from external files at high throughput
• 5MADlib library for in-database machine learning on distributed data

How Python Data Engineers Use Greenplum

Python data engineers use Greenplum's PL/Python extension to run Python transformation logic directly inside the database — writing Python UDFs that execute in parallel across all Greenplum segments. This in-database Python execution avoids moving large datasets out of Greenplum for transformation, keeping all processing co-located with the data.
