AWS::IoTAnalytics::Dataset DeltaTime - AWS CloudFormation

AWS::IoTAnalytics::Dataset DeltaTime

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


To declare this entity in your AWS CloudFormation template, use the following syntax:


{ "OffsetSeconds" : Integer, "TimeExpression" : String }


OffsetSeconds: Integer TimeExpression: String



The number of seconds of estimated in-flight lag time of message data. 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.
