AWS::IoTAnalytics::Dataset DeltaTime

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

Syntax

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

JSON

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

YAML

  OffsetSeconds: Integer
  TimeExpression: String

Properties

OffsetSeconds

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.

Required: Yes

Type: Integer

Update requires: No interruption

TimeExpression

An expression by which the time of the message data might be determined. 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.

Required: Yes

Type: String
