CData Python Connector for Amazon Athena

Build 21.0.7929

From Petl

The provider can be used to create ETL applications and pipelines for CSV data in Python using Petl.

Install Required Modules

Install the Petl modules using the pip utility.

pip install petl


Import the modules, including the CData Python Connector for Amazon Athena. You can then use the provider's connect function to create a connection using a valid Amazon Athena connection string. A SQLAlchemy engine may also be used instead of a direct connection.

import petl as etl
import cdata.amazonathena as mod
cnxn = mod.connect("AWSAccessKey='a123';AWSSecretKey='s123';AWSRegion='IRELAND';Database='sampledb';S3StagingDirectory='s3://bucket/staging/';")

Extract, Transform, and Load the Amazon Athena Data

Create a SQL query string and store the query results in a DataFrame.

sql = "SELECT	Name, TotalDue FROM Customers "
table1 = etl.fromdb(cnxn,sql)

Loading Data

With the query results stored in a DataFrame, you can load your data into any supported Petl destination. The following example loads the data into a CSV file.
