Python コネクタと NumPy の連携

以下は、Python コネクタと NumPy を連携する例です。

>>>  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)

結果は、以下のとおりです。
