-----------------------------------

[~markap14] [~mattyb149] I see matt was looking at other record related updates. Will this get reviewed with that or should we move off of 1.9.0?

> 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'}}
