Hi Nifi Community, I have situation where I need to merge JSON content from multiple flowfiles into one JSON content (single flowfile).
JSON in every flowfile looks like this: { "analyses": "prep_array", "args": "prep_array", "scriptId": "142", "libIds": "141", "job_name": "my_demo_job", "project_id": "23", "configId": "5", "file_id": "150", "analysis_name": "my_analysis_name", "source_id": "12", "customer_id": "16" } and every flowfile has only one filed different from the others, that is file_id. I want to merge it all in one JSON but to get this structure: { "analyses": "prep_array", "args": "prep_array", "scriptId": "142", "libIds": "141", "job_name": "my_demo_job", "project_id": "23", "configId": "5", "file_id": [ 150, 151, 152, 153, 154 ], "analysis_name": "my_analysis_name", "source_id": "12", "customer_id": "16" } What is the best way to do it? It sounds to me a little bit tricky, but I hope I'm wrong. Please can someone give me advice or some guidelines? Thanks in advance, Tom
