March 17, 2025
This release introduced UserDB Activated Static Parameters' Forecast Syncing (BETA), ensuring that activation parameters for UserDB destinations are instantly accessible for forecasting.
UserDB Activated Static Parameters' Forecast Syncing (BETA)
UserDB destination's activation parameters can now be synced with Forecast upon activation, making them immediately available for predictions.

Beware, only static attributes or segments, whose values should not change over time, should be toggled here. Sending dynamic properties to Forecast will hinder their prediction performance. You can see some examples of what should constitute a dynamic property in the destination's documentation.
