Is there a way to split one event into multiple events according to custom logic?

[zmingz123]

Hi there，
I want to split one event into multiple events according to custom logic, like Record Split in Fluent-bit.
for example：
input:

{
"a":"11",
"b":"11",
"c":"11",
"d":"11",
"extra":[
{"aa":"1"},
{"bb":"2}
]
}

target output:

{"a":"11","b":"11","c":"11","d":"11","aa":"1"}
{"a":"11","b":"11","c":"11","d":"11","bb":"2"}

I tried parse_json but it seems can only handle arrays

I think unnest may cover this for you:

. = unnest!(.extra)
