What Is Super Data Type Redshift?


Angela Bailey

The Super Data Type in Amazon Redshift is a powerful feature that allows users to store and manipulate large amounts of data efficiently. It is specifically designed to handle complex data types, making it a preferred choice for analytical workloads.

What is a Super Data Type?

A Super Data Type in Redshift is a collection of one or more columns with the same data type. It provides a way to group related columns together, making it easier to organize and query data. This can be particularly useful when dealing with wide tables or nested structures.

Benefits of Using Super Data Types

  • Improved Performance: By grouping related columns together, Redshift can optimize storage and query execution. This can lead to significant performance improvements, especially when dealing with large datasets.
  • Easier Data Manipulation: Super Data Types allow you to perform operations on multiple columns at once, simplifying complex queries and reducing the need for manual intervention.
  • Flexible Schema Design: With Super Data Types, you can easily add or remove columns without impacting existing queries. This flexibility makes it easier to adapt your schema as your data requirements evolve.

Working with Super Data Types

To create a Super Data Type in Redshift, you need to define the individual columns that make up the type and then group them together using the CREATE TYPE statement. Here’s an example:

CREATE TYPE address_type AS (
  street VARCHAR(100),
  city VARCHAR(50),
  state CHAR(2),
  zip VARCHAR(10)

In this example, we define an address_type that consists of four columns: street, city, state, and zip. Each column has its own data type specified.

Once the Super Data Type is defined, you can use it to create tables or add columns to existing tables. For example:

CREATE TABLE customers (
  customer_id INT,
  customer_name VARCHAR(100),
  shipping_address address_type

In this case, the shipping_address column is of type address_type. This allows you to store complex address information in a structured manner.

Querying Super Data Types

To query Super Data Types, you can use the dot notation to access individual columns within the type. For example:

SELECT customer_name, shipping_address.street, shipping_address.city
FROM customers;

This query retrieves the customer_name, street, and city columns from the customers table. By specifying the Super Data Type name followed by a dot, you can access specific columns within the type.


The Super Data Type in Amazon Redshift provides a flexible and efficient way to handle complex data structures. By grouping related columns together, it improves performance, simplifies data manipulation, and allows for flexible schema design. Understanding how to create and query Super Data Types can greatly enhance your analytical workflows in Redshift.
