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, start with the installation instructions, then follow our tutorial series.

If you have any questions, feedback, or feature requests, please let us know on Slack!
