-- | Defines an action to write to the Amazon DynamoDB table that you
-- created. The standard action payload contains all the information about
-- the detector model instance and the event that triggered the action. You
-- can customize the
-- <https://docs.aws.amazon.com/iotevents/latest/apireference/API_Payload.html payload>.
-- One column of the DynamoDB table receives all attribute-value pairs in
-- the payload that you specify.
--
-- You must use expressions for all parameters in @DynamoDBAction@. 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 @hashKeyType@ parameter can be
--     @\'STRING\'@.
--
-- -   For references, you must specify either variables or input values.
--     For example, the value for the @hashKeyField@ parameter can be
--     @$input.GreenhouseInput.name@.
--
-- -   For a substitution template, you must use @${}@, 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 @hashKeyValue@ parameter
--     uses a substitution template.
--
--     @\'${$input.GreenhouseInput.temperature * 6 \/ 5 + 32} in Fahrenheit\'@
--
-- -   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
-- <https://docs.aws.amazon.com/iotevents/latest/developerguide/iotevents-expressions.html Expressions>
-- in the /AWS IoT Events Developer Guide/.
--
-- If the defined payload type is a string, @DynamoDBAction@ writes
-- non-JSON data to the DynamoDB table as binary data. The DynamoDB console
-- displays the data as Base64-encoded text. The value for the
-- @payloadField@ parameter is @\<payload-field>_raw@.
