To configure the connection settings for SFTP dialogues in PDI, you must create either variables or parameters for each relevant value. Possible values are determined by the VFS driver you are using.
You can also use parameters to substitute VFS connection details, then use them in the VFS dialogue where appropriate. For instance, these would be relevant credentials, assuming the parameters have been set:
This technique enables you to hide sensitive connection details, such as usernames and passwords.
See VFS Properties for more information on VFS options. You can also see all of these techniques in practice in the VFS Configuration Sample sample transformation in the /data-integration/samples/transformations/ directory.
