Importing and exporting data with TLS

Vertica uses TLS to secure connections and communications between clients and servers. When you import or export data between Vertica clusters, one of the clusters functions as a client, which means you can use TLS to protect that connection, too.

The ImportExportTLSMode parameter controls the strictness of TLS when importing or exporting data.

By default, ImportExportTLSMode is set to PREFER. With this setting, Vertica attempts to use TLS and falls back to plaintext; you can change this to always require encryption and, further, to validate the certificate on each connection. For more information about TLS during import and export operations, see Configuring connection security between clusters.
