## What it is
Apache Cloudberry is an advanced open-source Massively Parallel Processing (MPP) database derived from Greenplum and built on a modern PostgreSQL kernel. It serves as a data warehouse for large-scale analytics, supporting distributed queries, multiple storage formats, and in-database AI/ML workloads.

## Use cases
- run a petabyte-scale data warehouse on commodity hardware
- migrate an existing Greenplum database to an open-source alternative
- run large-scale OLAP analytics with distributed parallel queries
- do in-database machine learning with MADlib on a Postgres-compatible MPP engine
- run spatial analytics with PostGIS at scale
- analyze unstructured data in object storage with SQL via directory tables
- serve near-real-time analytics with dynamic tables and hybrid PAX storage

## When to choose
- you need a Greenplum-compatible MPP data warehouse with a newer PostgreSQL kernel
- you want vendor-neutral Apache-governed open-source analytics database
- you need mixed workloads including spatial, ML, and OLAP in one engine
- you are scaling PostgreSQL-style analytics beyond a single node

## When to avoid
- you need a simple single-node OLTP database where plain PostgreSQL suffices
- you require a fully graduated, non-incubating Apache project
- your workload is small and does not benefit from MPP distribution
- you need managed cloud-native serverless analytics rather than self-hosted infrastructure
