How to Build an ETL App for BenchmarkEmail Data in Python with CData

The rich ecosystem of Python modules lets you get to work quickly and integrate your systems more effectively. With the CData API Driver for Python and the petl framework, you can build BenchmarkEmail-connected applications and pipelines for extracting, transforming, and loading BenchmarkEmail data. This article shows how to connect to BenchmarkEmail with the CData Python Connector and use petl and pandas to extract, transform, and load BenchmarkEmail data.

With built-in, optimized data processing, the CData Python Connector offers unmatched performance for interacting with live BenchmarkEmail data in Python. When you issue complex SQL queries from BenchmarkEmail, the driver pushes supported SQL operations, like filters and aggregations, directly to BenchmarkEmail and utilizes the embedded SQL engine to process unsupported operations client-side (often SQL functions and JOIN operations).

Connecting to BenchmarkEmail Data

Connecting to BenchmarkEmail data looks just like connecting to any relational data source. Create a connection string using the required connection properties. For this article, you will pass the connection string as a parameter to the create_engine function.

Start by setting the Profile connection property to the location of the BenchmarkEmail Profile on disk (e.g. C:\profiles\Benchmarkemail.apip). Next, set the ProfileSettings connection property to the connection string for BenchmarkEmail (see below).

BenchmarkEmail API Profile Settings

Navigate to Integrations > API Key in your BenchmarkEmail account to obtain the API Key.

After installing the CData BenchmarkEmail Connector, follow the procedure below to install the other required modules and start accessing BenchmarkEmail through Python objects.

Install Required Modules

Use the pip utility to install the required modules and frameworks:

pip install petl
pip install pandas

Build an ETL App for BenchmarkEmail Data in Python

Once the required modules and frameworks are installed, we are ready to build our ETL app. Code snippets follow, but the full source code is available at the end of the article.

First, be sure to import the modules (including the CData Connector) with the following:

import petl as etl
import pandas as pd
import cdata.api as mod

You can now connect with a connection string. Use the connect function for the CData BenchmarkEmail Connector to create a connection for working with BenchmarkEmail data.

cnxn = mod.connect("Profile=C:\profiles\Benchmarkemail.apip;ProfileSettings='APIKey=your_api_key';")

Create a SQL Statement to Query BenchmarkEmail

Use SQL to create a statement for querying BenchmarkEmail. In this article, we read data from the ABTestDetails entity.

sql = "SELECT Id, Name FROM ABTestDetails WHERE Status = 'Active'"

Extract, Transform, and Load the BenchmarkEmail Data

With the query results stored in a DataFrame, we can use petl to extract, transform, and load the BenchmarkEmail data. In this example, we extract BenchmarkEmail data, sort the data by the Name column, and load the data into a CSV file.

Loading BenchmarkEmail Data into a CSV File

table1 = etl.fromdb(cnxn,sql)

table2 = etl.sort(table1,'Name')

etl.tocsv(table2,'abtestdetails_data.csv')

With the CData API Driver for Python, you can work with BenchmarkEmail data just like you would with any database, including direct access to data in ETL packages like petl.
