Trifacta client

trifacta

Trifacta client that makes it easy to integrate Trifacta into your production and data science workflows

Usage Scenarios

• Jupyter: Invoke Trifacta jobs from a Jupyter notebook and pass data back and forth between Jupyter and Trifacta
• Other Notebooks: Integrate Trifacta with Azure Databricks, Zepellin or any other notebook-style interface that supports Python
• Scripts: Automate Trifacta jobs and input/output using python scripts that can be easily executed from the command line or called from an external scheduler

Functionality

This library makes it simple to do the following:

1. Connect to a Trifacta instance
2. Run a job
3. Download results to a pandas dataframe OR Download results as text/csv
4. Upload files to Trifacta

Note that file uploads and downloads are performed using httpfs, and require that port 14000 be opened on the Trifacta server

#!pip install trifacta
import trifacta

#Step 1: Connect to Trifacta by providing the URL, username and password
t = trifacta.Client('https://partnerdemo.trifacta.net', '[e-mail]', 'mypassword')

Get the wrangled dataset id from the URL in the Trifacta UI

Make sure that you have run the job manually at least once

Note the output path (be sure to set it to "replace")

#Step 2: Run the job
t.run_job(14478)
