Integrating the Python connector with NumPy - Amazon Redshift

Amazon Redshift will no longer support the use of Python UDFs after June 30, 2026. We will start enforcing it in phases. For more information on the details of Python end of life and migration options, see the blog post that was published on June 30, 2025.

Integrating the Python connector with NumPy

Following is an example of integrating the Python connector with NumPy.

>>>  import numpy
#Connect to the cluster
>>> import redshift_connector
>>> conn = redshift_connector.connect(
     host='examplecluster.abc123xyz789.us-west-1.redshift.amazonaws.com',
     port=5439,
     database='dev',
     user='awsuser',
     password='my_password'
  )
  
# Create a Cursor object
>>> cursor = conn.cursor()

# Query and receive result set            
cursor.execute("select * from book")

result: numpy.ndarray = cursor.fetch_numpy_array()
print(result)

Following is the result.
