inputPathoptionalstringinput_pathoptionalstrinputPathoptionalStringInputPathoptionalstringInputPathoptional*string= $#
JSONPath expression to select part of the state to be the input to this state.

May also be the special value JsonPath.DISCARD, which will cause the effective input to be the empty object {}.

AWS Step Functions integrates with services directly in the Amazon States Language.

Default: IntegrationPattern.REQUEST_RESPONSE for most tasks. IntegrationPattern.RUN_JOB for the following exceptions: BatchSubmitJob, EmrAddStep, EmrCreateCluster, EmrTerminationCluster, and EmrContainersStartJobRun.

You can control these AWS services using service integration patterns.

Depending on the AWS Service, the Service Integration Pattern availability will vary.

Primary key of the item to retrieve.
notes

For the primary key, you must provide all of the attributes. For example, with a simple primary key, you only need to provide a value for the partition key. For a composite primary key, you must provide values for both the partition key and the sort key.

outputPathoptionalstringoutput_pathoptionalstroutputPathoptionalStringOutputPathoptionalstringOutputPathoptional*string= $#

May also be the special value JsonPath.DISCARD, which will cause the effective output to be the empty object {}.

outputsoptionalanyoutputsoptionalAnyoutputsoptionalObjectOutputsoptionalobjectOutputsoptionalinterface{}#
Used to specify and transform output from the state.

Default: $states.result or $states.errorOutput

notes

When specified, the value overrides the state output default. The output field accepts any JSON value (object, array, string, number, boolean, null). Any string value, including those inside objects or arrays, will be evaluated as JSONata if surrounded by {% %} characters. Output also accepts a JSONata expression directly.

JSONPath expression to indicate where to inject the state's output.

May also be the special value JsonPath.DISCARD, which will cause the state's input to become its output.
