-------------------------------
Summary: Support for handling JSON nested arrays
Key: NIFI-7077
URL: https://issues.apache.org/jira/browse/NIFI-7077
Project: Apache NiFi
Issue Type: Wish
Affects Versions: 1.9.2
Reporter: Jim Huang
I am a new Nifi user with very limited knowledge of Nifi's breadth and depth.
I have a need to parse a JSON with 4 levels of nested ARRAY and extracting that
child node which is also an ARRAY.
>From my quick research since Nifi 1.7.0+, Janway's JsonPath 2.4.0 have been
>integrated via NIFI-5169. However Janway's JsonPath has [an open
>issue|[https://github.com/json-path/JsonPath/issues/287]] parsing nested
>ARRAYs with a filter. According to this stack overflow question, Gatling's
>implementation is able to solve this
>[issue|https://stackoverflow.com/a/46419991].
The current Nifi guide on JsonPath example doesn't provide
[example|[https://nifi.apache.org/docs/nifi-docs/html/expression-language-guide.html#jsonpath]]
on extracting targeted child node located at the bottom of the nested ARRAYs.
What are some options that are currently available or potential near term
enhancements that can be drafted up to have some building blocks that can
eventually solve this goal?
Thanks!
