Explore the schema

Create an external data source

Here are the steps to create a external data source with the AWS Redshift connector:

Sign in to the Incorta Direct Data Platform.
In the Navigation bar, select Data.
In the Action bar, select + New → Add Data Source.
In the Choose a Data Source dialog, in Database, select RedShift.
In the New Data Source dialog, specify the applicable connector properties.

AWS Redshift connector properties

Here are the properties for the AWS Redshift connector:

Property	Control	Description
Data Source Name	text box	Enter the name of the data source
Username	text box	Enter the Redshift database username
Password	text box	Enter the Redshift database password
Connection Pool	text box	Enter the connection pool. The default is 30.
Connection String	text box	Enter the connection string for the Redshift JDBC driver. The format is: `jdbc:redshift://<HOST>:<PORT><DB>` The default port is 5439.
Connection Properties	text box	Optionally enter connector properties for a custom connection to AWS Redshift in the format: `propertyName=propertyValue`, where each connector property is on a new line. The available connector properties are specified by `com.amazon.redshift.jdbc4.Driver`. Refer to the Driver Configuratio Options section of the Amazon Redshift JDBC Driver Installation and Configuration Guide for further information.
Extra Options	text box	Enter supported extra options in the form of `key=value`.
Use Data Agent	toggle	Enable using a data agent to securely ingest data from an external data source that is behind a firewall. For more information, please review Tools → Data Agent and Tools → Data Manager.
Data Agent	drop down list	Enable Use Data Agent to configure this property. Select from the data agents created in the tenant, if any.

Important: Data Agent

A data agent is a service that runs on a remote host. It is also a data agent object in the Data Manager for a given tenant. An authentication file shared between the data agent object and the data agent service enables an authorized connection without using a VPN or SSH tunnel. With a data agent, you can securely extract data from one or more databases behind a firewall to an Incorta cluster. Your Incorta cluster can reside on-premises or in the cloud.

You must have the Incorta cluster enabled and configured to support the use of Data Agents. To learn more, see Concepts → Data Agent and Tools → Data Agent.
