Redshift Handler

This is the implementation of the Redshift handler for MindsDB.

​

Redshift

Amazon Redshift is a fully managed, petabyte-scale data warehouse service in the cloud. You can start with just a few hundred gigabytes of data and scale to a petabyte or more. This enables you to use your data to acquire new insights for your business and customers. https://docs.aws.amazon.com/redshift/latest/mgmt/welcome.html

​

Implementation

This handler was implemented using the redshift_connector library that is provided by Amazon Web Services.

The required arguments to establish a connection are,

• host: the host name or IP address of the Redshift cluster
• port: the port to use when connecting with the Redshift cluster
• database: the database name to use when connecting with the Redshift cluster
• user: the user to authenticate the user with the Redshift cluster
• password: the password to authenticate the user with the Redshift cluster

​

Usage

Before attempting to connect to a Redshift cluster using MindsDB, ensure that it accepts incoming connections. The following can be used as a guideline to accomplish this, https://aws.amazon.com/premiumsupport/knowledge-center/cannot-connect-redshift-cluster

In order to make use of this handler and connect to a Redshift cluster in MindsDB, the following syntax can be used,

CREATE DATABASE redshift_datasource
WITH
engine='redshift',
parameters={
    "host": "examplecluster.abc123xyz789.us-west-1.redshift.amazonaws.com",
    "port": 5439,
    "database": "example_db",
    "user": "awsuser",
    "password": "my_password"
};

Now, you can use this established connection to query your database as follows,

SELECT * FROM redshift_datasource.example_tbl
