## Introduction

Apache Cloudberry (Incubating), created by the original developers of
Greenplum Database, is one advanced and mature open-source Massively Parallel
Processing (MPP) database, which evolves from the open-source version of the
Pivotal Greenplum Database®️ but features a newer PostgreSQL kernel and more
advanced enterprise capabilities. It can serve as a data warehouse and can
also be used for large-scale analytics and AI/ML workloads.

Sandbox](./devops/sandbox), which is tailored to help you gain a basic
understanding of Cloudberry's capabilities and features.

## ASF Incubator disclaimer

Apache Cloudberry is an effort undergoing incubation at The Apache Software
Foundation (ASF), sponsored by the Apache Incubator. Incubation is required
for all newly accepted projects until a further review indicates that the
infrastructure, communications, and decision making process have stabilized in
a manner consistent with other successful ASF projects. While incubation
status is not necessarily a reflection of the completeness or stability of the
code, it does indicate that the project has yet to be fully endorsed by the
ASF.
