This documentation describes the integration of MindsDB with Amazon Redshift, 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, enabling you to use your data to acquire new insights for your business and customers.

​
Prerequisites

Before proceeding, ensure the following prerequisites are met:

  1. Install MindsDB locally via Docker or Docker Desktop.
  2. To connect Redshift to MindsDB, install the required dependencies following this instruction.

​
Connection

Establish a connection to your Redshift database from MindsDB by executing the following SQL command:

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"
  };

Required connection parameters include the following:

  • 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 username to authenticate the user with the Redshift cluster.
  • password: The password to authenticate the user with the Redshift cluster.

Optional connection parameters include the following:

  • schema: The database schema to use. Default is public.
  • sslmode: The SSL mode for the connection.

​
Usage

Retrieve data from a specified table by providing the integration name, schema, and table name:

SELECT *
FROM redshift_datasource.schema_name.table_name
LIMIT 10;

Run Amazon Redshift SQL queries directly on the connected Redshift database:

SELECT * FROM redshift_datasource (

    --Native Query Goes Here
    WITH VENUECOPY AS (SELECT * FROM VENUE)
      SELECT * FROM VENUECOPY ORDER BY 1 LIMIT 10;

);

The above examples utilize redshift_datasource as the datasource name, which is defined in the CREATE DATABASE command.

Troubleshooting Guide

Database Connection Error

  • Symptoms: Failure to connect MindsDB with the Amazon Redshift cluster.
  • Checklist:
    1. Make sure the Redshift cluster is active.
    2. Confirm that host, port, user, password and database are correct. Try a direct Redshift connection using a client like DBeaver.
    3. Ensure that the security settings of the Redshift cluster allow connections from MindsDB.
    4. Ensure a stable network between MindsDB and Redshift.

SQL statement cannot be parsed by mindsdb_sql

  • Symptoms: SQL queries failing or not recognizing table names containing spaces or special characters.
  • Checklist:
    1. Ensure table names with spaces or special characters are enclosed in backticks.
    2. Examples:
      • Incorrect: SELECT * FROM integration.travel data
      • Incorrect: SELECT * FROM integration.‘travel data’
      • Correct: SELECT * FROM integration.`travel data`
