DynamoDBAction class
Defines an action to write to the Amazon DynamoDB table that you created. The standard action payload contains all attribute-value pairs that have the information about the detector model instance and the event that triggered the action. You can also customize the payload. One column of the DynamoDB table receives all attribute-value pairs in the payload that you specify.
The tableName and hashKeyField values must match
the table name and the partition key of the DynamoDB table.
The hashKeyValue and rangeKeyValue use
substitution templates. These templates provide data at runtime. The syntax
is ${sql-expression}.
You can use expressions for parameters that are string data type. For more information, see Expressions in the AWS IoT Events Developer Guide.
