Federated Analytics — Nodes

Overview

This page is for node operators. It explains how to enable or disable Federated Analytics (FA) on a node and what that means in practice.

Federated Analytics lets researchers compute statistics across data held by multiple nodes without the raw data ever leaving any node. When a researcher sends an analytics request, each node computes the statistics locally and sends back only the aggregated summaries.

• For which datasets support FA and how to make a custom dataset FA-compatible, see Federated Analytics — Datasets.
• For how to run analytics as a researcher, see Federated Analytics — Researcher.

Enabling or Disabling FA

Federated Analytics is enabled by default on every node. The setting lives in the [security] section of the node configuration file:

[security]
allow_federated_analytics = True

To disable FA on a node, set the value to False:

[security]
allow_federated_analytics = False

Once a dataset is registered on a node with the appropriate tags, it is automatically eligible for analytics requests — no further configuration is needed beyond this flag.
