Evaluate json for attribute

LuxIsterica — Fri, 11 Oct 2019 00:16:16 GMT

Hello,
I would like to implement this logic on nifi:
I have a json array:
[
{
"att1": "1",
"att2": "aaa"
},
{
"att1": "2",
"att2": "bbb"
},
{
"att1": "3",
"att2": "aaa"
},
]

I would like that, according to the attribute, the json was processed to the processA or to the processB.

For example, if att2 is equal "aaa", it was processed to the processA, else it was processed to the processB.
I tried to follow the suggestion of the following solution

https://community.cloudera.com/t5/Support-Questions/Nifi-processor-route-json-array-into-multiple-json-arrays/td-p/128722

but it didn't work. Can you give me an alternative?

Thank you.

Hi @LuxIsterica,

I would split your json (SplitJson) > EvaluateJsonPath ( To turn att2 to an attribute and call it an attribute name ) > RouteOnAttribute ( To see if the attribute name you grabbed equals to aaa ) > Route it either to you found a relationship or unmatched
