   Select a managed DB in the current Yandex Cloud organization and specify the internal network connection parameters for it:

   • Cloud and folder: Select the folder where the cluster is located.

   • Cluster: Specify a cluster from the list of available Greenplum® clusters. Cluster settings must have the DataLens access option enabled. If you do not have an available cluster, click Create new.

     Note

     The list shows the following clusters:

     • With permissions for the user who creates the connection.
     • Created in the same organization as the DataLens instance.

     • Special FQDNs: Allows you to select a special FQDN for connection, which always points to the primary Greenplum® master host.

   • Hostname: Select the host name from the list of hosts available in the Greenplum® cluster. You can select multiple hosts. If you are unable to connect to the first host, DataLens will select the next one from the list.

   • Path to database: Specify the name of the database to connect to.

   • Username: Specify the username for the Greenplum® connection.

   Manually specify the parameters of an external database to connect to via a public network:

   • Hostname: Specify the path to a master host or a Greenplum® master host IP address. You can specify multiple hosts in a comma-separated list. If you are unable to connect to the first host, DataLens will select the next one from the list.
   • Port: Specify the Greenplum® connection port. The default port is 5432.
   • Path to database: Specify the name of the database to connect to.
   • Username: Specify the username for the Greenplum® connection.
