Phase-out of WOS Support

Over the past several releases, Vertica has significantly improved small batch loading into ROS, which now provides WOS-equivalent performance. In order to simplify product usage, Vertica will phase out support for WOS-related functionality, starting with release 9.3.0.

History of Removed Functionality

These changes currently apply only to new databases. Until further notice, Vertica will maintain WOS support for databases that were created in earlier releases.

Functionality Removed in: Notes
DIRECT as default load type 9.3.0 Table data bypasses WOS and is loaded directly to ROS, bypassing WOS. Vertica ignores other load options and hints, such as TRICKLE.
WOSDATA resource pool disabled 9.3.0 The resources formerly assigned to this pool are now assigned to the TM pool. You can enable this resource pool with configuration parameter DMLTargetDirect.
SYSDATA resource pool disabled 9.3.0
