Dear Experts, We want to learn how to perform batch processing on semi-structured JSON flow files in NiFi. We know that we can use a Jolt Transform Record, an Update Record processor, and a Query Record processor, for which we need to set reader and writer controller services. However, we are unsure how to set up reader and writer controllers for semi-structured data schemas. In the text below, we have a multi-line JSON flow file in which the "code" field is static and the "other" field is an unstructured nested JSON. We want to query the "code" field in batch mode and include the "other" field information in the resulting flow files for processing in subsequent processors. How should we set the reader and writer controllers to achieve this? Regards, {"code": "6", "other": {"feild1": "data1"}} {"code": "7", "other": {"feild2": "data2"}} {"code": "8", "other": {"feild3": "data3"}}
