What: Segments with zero device population for the last 30 consecutive refreshes will be moved to on-demand refresh cadence. And segments that were modified more than a year ago and not activated will also be moved to on-demand refresh cadence. This change will improve both system reliability and performance.
Why: As more segments are created, the platform takes more time to process all the segments. Unused segments will not be processed frequently so that the platform resources are efficiently utilized to process the segments that are used for Analytics or Targeting. To reliably process the segments that are used for Analytics or Targeting, unused segments will be moved to on-demand refresh cadence to efficiently utilize the platform resources.
When: On January 29, 2020, the refresh cadence of unused segments will be changed to on-demand.
