Platform Extension Framework (PXF) for Apache Cloudberry
The Apache Cloudberry Platform Extension Framework (PXF) provides parallel, high throughput data access and federated queries across heterogeneous data sources via built-in connectors that map an Apache Cloudberry external table definition to an external data source. PXF has its roots in the Apache HAWQ project.
Apache Cloudberry PXF is derived from the now-archived greenplum-db/pxf-archive project (at version 6.10.1-SNAPSHOT). It has been extensively customized and optimized for Apache Cloudberry, and now evolves independently with its own release cadence.
This documentation is derived from the original greenplum-db/pxf-archive 6.10.1 documentation. Content has been added, revised, and removed to reflect the actual behavior of Apache Cloudberry PXF.
