> Record Path functions to un/escape JSON
> ---------------------------------------
>
> Key: NIFI-8137
> URL: https://issues.apache.org/jira/browse/NIFI-8137
> Project: Apache NiFi
> Issue Type: Improvement
> Affects Versions: 1.11.4
> Reporter: Chris Sampson
> Assignee: Chris Sampson
> Priority: Major
> Time Spent: 10m
> Remaining Estimate: 0h
>
> Record Path functions to:
> * unescape JSON contained within a String field and put the resulting Record
> fields into the data, e.g. UpdateRecord for {{/}} =>
> {{unescapeJson(/stringified_json)}} would unescape JSON String in
> {{/stringified_json}} and put the resulting Object fields into the top-level
> of the Record
> * collect one or more Record fields into an Object that is put into a single
> stringified JSON field, e.g. UpdateRecord for {{/stringified_json}} =>
> {{escapeJson( / )}} would do the reverse of the above
> These would be equivalent to the existing Expression Language functions, but
> mean there was no need to split records into individual flowfiles, extract
> the field from the content into an attribute, unescape the JSON then replace
> the text back into the content and re-merge all the records (which is fidly
> and resource expensive).
