Sure. Thank you.
Processor #1 creates this JSON
{
"name":"this and that",
"field":"value"
}
passes to Processor #2 which adds a record to a sub-field
{
"name":"this and that",
"field":"value",
"others": [
{"name":"here and there"}
]
}
passes to Processor #3 which also adds a record to "others".
{
"name":"this and that",
"field":"value",
"others": [
{"name":"here and there"},
{"name":"one and two"},
]
}
which is the final output. So it's more building a JSON than transforming,
sorta.

Can you post example of input and expected result.
For adding, you can use default or modify-overwrite-beta

Hi. Thank you.
In looking at the Jolt docs these are the operations:
shift, sort, cardinality, modify-default-beta, modify-overwrite-beta,
modify-define-beta, or remove
I primarily need "add" such that I can add nested elements or add elements to
an array already in the JSON.
Can a single Jolt processor do this? Or do I need to merge two inputs to join
them into a single JSON?
thanks in advance!
Darren

Hi,
I want to use Nifi to design a flow that modifies, updates, etc a nested
JSON document (or that can finally output one at the end).
For example:
{
"name":"this and that",
"field":"value",
"others": [
{"name":"here and there"},
...
]
}
What's the best approach to this using Nifi?
Thanks in advance!
