Tumult Analytics documentation#

Tumult Analytics is a Python library for computing aggregate queries on tabular data using differential privacy.

Tumult Analytics is…

  • easy to use: its interface will seem familiar to anyone with prior experience with tools like SQL or PySpark.

  • feature-rich: it supports a large and ever-growing list of aggregation functions, data transformation operators, and privacy definitions.

  • robust: it is built and maintained by a team of differential privacy experts, and runs in production at institutions like the U.S. Census Bureau.

  • scalable: it runs on Spark, so it can scale to very large datasets.

For new users, this Colab notebook demonstrates basic features of the library without requiring a local installation. To explore further or work on larger datasets, a good starting point is the installation instructions.

The Tumult Analytics documentation introduces all of the concepts necessary to get started producing differentially private results. Users who wish to learn more about the fundamentals of differential privacy can consult this blog post series or this longer introduction.



Tutorials are the place where new users can learn the basics of how to use the library. No prior knowledge of differential privacy is required!
