Hello all, I am trying to use QueryRecord processor to filter a json file but i am getting 0kb flowfile on my filter relationship. My input flowfile is: { "data": [ { "room": "A", "path": "/old/can" }, { "room": "B", "path": "/old/can" }, { "room": "C", "path": "/old/can" } ] } My filter query: SELECT * FROM FLOWFILE WHERE RPATH_STRING(data, '/room[*]')='${'ip'}' NOTE: ip is an attribute using to compare which class to filter, so if ip = A my output after filtering should be { "data": [ { "room": "A", "path": "/old/can" } ] } Thank you all.

I am very grateful for your help so far sir @SAMSAL. Actually, i made a silly mistake concerning that key duplication. I wanted to have something of this nature, that is separate objects each with "Details" topmost level. "Details" : {
"0":{
"test1" : "test output",
"test2" : "test output",
"id" : "first",
"name" : "the first one"
}},
"Details":{
"1":{
"test1" : "test output",
"test2" : "test output",
"id" : "second",
"name" : "the second one"
}}

Thank you sir @SAMSAL . Actually the desired output is {
"Details" : { "0":{
"test1" : "test output",
"test2" : "test output",
"id" : "first",
"name" : "the first one"
}}, "Details":{ "1":{
"test1" : "test output",
"test2" : "test output",
"id" : "second",
"name" : "the second one"
}}
}
