[jira] [Updated] (NIFI-5903) Allow RecordPath to be used in order to access nested fields within QueryRecord

     [ https://issues.apache.org/jira/browse/NIFI-5903?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Mark Payne updated NIFI-5903:
-----------------------------
    Description: 
QueryRecord is an immensely powerful tool when evaluating "flat" data such as CSV or flattened JSON. However, when evaluating data that has a lot of nested elements, it loses a lot of its power quickly because there is no way to query those nested elements. We should enable users to use RecordPath to pull out particular fields of a Record so that we can write queries like:

{{SELECT *}}
{{FROM FLOWFILE}}
{{WHERE RPATH(organization, '/department/name') = 'Research and Engineering'}}
