About Vertica Connection Guides
Vertica connection guides provide basic information about setting up connections to Vertica from software that our technology partners create. These documents provide guidance using one version of Vertica and one version of the third party vendor’s software. Other versions of the third-party product may work with Vertica. However, we may not have tested those other versions.
