DeltaTimeProperty Struct
Used to limit data to that which has arrived since the last execution of the action.

Properties

notes
When you create dataset contents using message data from a specified timeframe, some message data might still be in flight when processing begins, and so do not arrive in time to be processed. Use this field to make allowances for the in flight time of your message data, so that data not processed from a previous timeframe is included with the next timeframe. Otherwise, missed message data would be excluded from processing during the next timeframe too, because its timestamp places it within the previous timeframe.

This can be the name of a timestamp field or a SQL expression that is used to derive the time the message data was generated.
