The change data capture (CDC) operation returns a list of entities that have changed since a specified time. This operation is for an app that periodically polls Data Services and then refreshes its local copy of entity data. The app calls the cdc operation, specifying a list of entity types and a DateTime stamp. Data Services returns all objects specified by entityNameList that have changed since the specified date-time. There is no limit on the number of rows on CDCQuery. As the limit is date-based, data that has been accumulated for more than 5 days cannot be used. The service may fail if you are requesting for data that is older than 5 days.
