Deprecated and Removed Functionality

This section describes the two phases Vertica follows to retire Vertica functionality:

  • Deprecated: Vertica announces deprecated features and functionality in a major or minor release. Deprecated features remain in the product and are functional. Published release documentation announces deprecation on this page. When users access this functionality, it may return informational messages about its pending removal.
  • Removed: Vertica removes a feature in a major or minor release that follows the deprecation announcement. Users can no longer access the functionality, and this page is updated to verify removal (see History, below). Documentation that describes this functionality is removed, but remains in previous documentation versions.

Deprecated

The following Vertica functionality was deprecated and will be retired in a future Vertica version:

Release Functionality Notes

DisableDirectToCommunalStorageWrites configuration parameter Superseded by UseDepotForWrite
ReuseDataConnections configuration parameter  
Mac 10.11 Client driver
  Vertica Python Client Replaced with Vertica open source Python adapter
  32-bit ODBC Linux and OS X client drivers  
9.2

Network interfaces

 Superseded by network addresses, which are a more flexible way to define node network connections.
Database Branching  

Configuration parameters:

  • EnableExprsInProjections
  • EnableGroupByProjections
  • EnableTopKProjections
  • EnableUDTProjections
 Parameters that enabled projections with pre-aggregated data. In future releases, projections of this type will always be enabled.

Removed

The following functionality is no longer accessible as of the releases noted:

Release Functionality Notes
9.2 Pre-join projections

Vertica no longer supports existing projections of either type. Attempts to upgrade from a database with either projection type will fail. Before upgrade, run the pre-upgrade script to identify these projections, and then remove or replace them.
