Creating a Password Datasource Authentication

Scenario

Create a password datasource authentication on the DLI console to store passwords of the GaussDB(DWS), RDS, DCS, and DDS data sources to DLI. This will allow you to access to the data sources without having to configure a username and password in SQL jobs.

Data Sources Supported by Password Datasource Authentication

Table 1 lists the data sources supported by password datasource authentication.
