MapBaseOptions Struct
Base properties for defining a Map state.
Example
ts
// The code below shows an example of how to instantiate this type.
// The values are placeholders you should change.
import { aws_stepfunctions as stepfunctions } from 'aws-cdk-lib';
declare const assign: any;
declare const itemSelector: any;
const mapBaseOptions: stepfunctions.MapBaseOptions = {
assign: {
assignKey: assign,
},
itemSelector: {
itemSelectorKey: itemSelector,
},
jsonataItemSelector: 'jsonataItemSelector',
jsonataMaxConcurrency: 'jsonataMaxConcurrency',
maxConcurrency: 123,
};
