Struct rusoto_iotevents::DynamoDBv2Action
source · [−]Expand description
Defines an action to write to the Amazon DynamoDB table that you created. The default action payload contains all the information about the detector model instance and the event that triggered the action. You can customize the payload. A separate column of the DynamoDB table receives one attribute-value pair in the payload that you specify.
You must use expressions for all parameters in DynamoDBv2Action
. The expressions accept literals, operators, functions, references, and substitution templates.
Examples
-
For literal values, the expressions must contain single quotes. For example, the value for the
tableName
parameter can be'GreenhouseTemperatureTable'
. -
For references, you must specify either variables or input values. For example, the value for the
tableName
parameter can be$variable.ddbtableName
. -
For a substitution template, you must use
${}
, and the template must be in single quotes. A substitution template can also contain a combination of literals, operators, functions, references, and substitution templates.In the following example, the value for the
contentExpression
parameter inPayload
uses a substitution template.'{\"sensorID\": \"${$input.GreenhouseInput.sensor_id}\", \"temperature\": \"${$input.GreenhouseInput.temperature * 9 / 5 + 32}\"}'
-
For a string concatenation, you must use
+
. A string concatenation can also contain a combination of literals, operators, functions, references, and substitution templates.In the following example, the value for the
tableName
parameter uses a string concatenation.'GreenhouseTemperatureTable ' + $input.GreenhouseInput.date
For more information, see Expressions in the AWS IoT Events Developer Guide.
The value for the type
parameter in Payload
must be JSON
.
Fields
payload: Option<Payload>
table_name: String
The name of the DynamoDB table.
