Presto Connection

See the Connector Marketplace topic. Please request your administrator to start a trial or subscribe to the Premium Presto connector.

Presto lets you search large amounts of data with SQL. It works with multiple data sources like Hadoop and Cassandra.

This topic describes how to authenticate to Presto and configure any necessary connection properties in the Presto connection connector.

Connection Configuration #

Each connection property available in the Presto connector is explained below.

Connection Name #

The name of the connection to be created should be provided. This is the name that will display on the list of available connections.

Connection Type #

Option to choose between either connecting securely using SSH Tunnel or, proceed with a direct connection when connecting to Presto.

If Connection Type value is SSH Tunnel, additional fields will be displayed.

To know more about SSH Tunneling with Gathr, see SSH Tunneling

SSH Tunnel #

If SSH Tunnel is selected, additional configuration parameters will get listed.

SSH Key #

The SSH key should be provided to authenticate the associated SSH host and SSH user.

SSH Host #

Public IP address of your SSH host.

SSH User #

Default SSH username.

If Connection Type value is Direct Connection, then proceed by updating the following fields.

The scheme used for authentication. Accepted entries are:

• None: No authentication is performed, default.

After entering all the details, click on the TEST button.

If the connection service identification and authentication details are provided correctly, a success message stating “connection available” is generated.

Click on the CREATE button to save the changes.

If the details are incorrect or the server is down, you will get a message “Connection unavailable”.
