Example

// The code below shows an example of how to instantiate this type.
// The values are placeholders you should change.
import * as s3tables_alpha from '@aws-cdk/aws-s3tables-alpha';

declare const icebergTransform: s3tables_alpha.IcebergTransform;
const icebergPartitionField: s3tables_alpha.IcebergPartitionField = {
  name: 'name',
  sourceId: 123,
  transform: icebergTransform,

  // the properties below are optional
  fieldId: 123,
};
