---------------------------------
Assignee: Peter Gyori
> Optional removal of fields with UpdateRecord
> --------------------------------------------
>
> Key: NIFI-8243
> URL: https://issues.apache.org/jira/browse/NIFI-8243
> Project: Apache NiFi
> Issue Type: Improvement
> Components: Extensions
> Reporter: Pierre Villard
> Assignee: Peter Gyori
> Priority: Major
>
> Improve the UpdateRecord processor for field removal:
> * *Improvement 1* - In case, "Replacement Value Strategy" is set to "Record
> Path Value", then add a boolean property that would default to false and if
> true would remove the fields provided in the dynamic properties after the
> updates have been done. This would provide the capability to move fields in
> the schema.
> * *Improvement 2* - In case, "Replacement Value Strategy" is set to "Record
> Path Value", allow the users to set the empty string as the value of the
> paths provided through dynamic properties. This would provide the capability
> to remove fields.
> Example - *input*
>
> {code:java}
> {
> "foo": "value",
> "record": {
> "subrecord": {
> "key": "value"
> }
> }
> }{code}
> *Improvement 1*
> *Dynamic property: /subrecord => /record/subrecord*
> *Additional property set to true*
> *Output*
> {code:java}
> {
> "foo": "value",
> "subrecord": {
> "key": "value"
> }
> }{code}
>
> *Improvement 2*
> *Dynamic property: /record => <empty string>*
> *Output*
> {code:java}
> {
> "foo": "value"
> }{code}
>
