Effective in version 10.2.1, you can use the intelligent structure model in Big Data Management.
Spark Engine Support for Data Objects with Intelligent Structure Model
You can incorporate an intelligent structure model in an Amazon S3, Microsoft Azure Blob, or complex file data object. When you add the data object to a mapping that runs on the Spark engine, you can process any input type that the model can parse.
The data object can accept input and parse PDF forms, JSON, Microsoft Excel, Microsoft Word tables, CSV, text, or XML input files, based on the file which you used to create the model.
Intelligent structure model in the complex file, Amazon S3, and Microsoft Azure Blob data objects is available for technical preview. Technical preview functionality is supported but is unwarranted and is not production-ready. Informatica recommends that you use these features in non-production environments only.
