I would make the same comment here as above, regarding the phrasing that
the flow file content need not be well-formed JSON.
> Update JSON Record Reader / Writer to allow for 'json per line' format

> Issue Type: Improvement

> Assignee: Matt Burgess
> Priority: Major
>
> It is common, especially for archiving purposes, to have many JSON objects
> combined with new-lines in between, in order to delimit the records. It would
> be useful to allow record readers and writers to support this, instead of
> requiring that JSON records being elements in a JSON Array.
> For example, the following JSON Is considered two records:
> {code}
> [
> { "greeting" : "hello", "id" : 1 },
> { "greeting" : "good-bye", "id" : 2 }
> ]
> {code}
> It would be beneficial to also support the format:
> {code}
> { "greeting" : "hello", "id" : 1 }
> { "greeting" : "good-bye", "id" : 2 }
> {code}
