About this Documentation

Source code for the Greenplum Database documentation is shared between Greenplum Database and VMware Tanzu Greenplum. Some features of Tanzu Greenplum are not present in the open source Greenplum Database code but are described in the Greenplum Database documentation.

In general, the term “Tanzu Greenplum” refers to VMware’s commercial, supported version of Greenplum Database and is used in this documentation when describing features that are only supported in the commercial Greenplum Database software. The term “Greenplum Database” refers to features available in both open source Greenplum Database and Tanzu Greenplum.

Features that are only supported with Tanzu Greenplum are noted in sections that contain primary documentation for the features.

The following is a list of Tanzu Greenplum features that are unsupported in open source Greenplum Database but may be documented or referenced in this documentation.

  • Code to produce the Tanzu Greenplum binary installer packages is not included in the open source Greenplum Database repository.

  • Greenplum Database does not include EMC DD Boost integration. Backing up to an EMC Data Domain appliance is only supported when the Data Domain system is mounted as an NFS share on the Greenplum hosts.

  • Greenplum Database does not include Symantec NetBackup integration.

  • The QuickLZ compression method is not available in Greenplum Database. QuickLZ compresstype values are ignored when specified in a CREATE TABLE [AS] operation, but will cause an error on subsequent INSERT or SELECT operations on the table.

  • The deprecated gpcheck management utility and its replacement gpsupport are only supported with Tanzu Greenplum.

  • Suggestions to contact VMware Technical Support in this documentation are intended only for Tanzu Greenplum customers.
