Hi,  I have a json in the below format [ { "order_id": 1, "category": 123 }, { "order_id": 2, "category": 123  }, { "order_id": 3, "category": 456 }, { "order_id": 4, "category": 321 } ]   I want to create flowfiles seperatly for all the categories, flowfile1 - orders of category 123: [ { "order_id": 1, "category": 123 }, { "order_id": 2, "category": 123  } ] flowfile2 - orders of category 456 [ { "order_id": 3, "category": 456 } ] flowfile3 - orders of category 321: [ { "order_id": 4, "category": 321 } ]   I don't want to use splitjson, because this will be applied on millions of records. I don't want millions of flowfiles. I tried EvaluateJsonPath and RouteOnAttribute all_category : $.[*].category - this creates on attribute with all category values RouteOnAttribute  category_123 : ${all_category:contains(123)} category_321 : ${all_category:contains(321)} category_456 : ${all_category:contains(456)} But all the 3 flowfiles routed has all the order details. Please guide me here, I am new to NIFI   ... View more
