Chris Sampson commented on NIFI-8133:
-------------------------------------
Upon further investigation, I was unable to get {{null}} fields output by
{{PutElasticsearchRecord}} in the current NiFi (I'm using 1.11.4, which led me
to raise this ticket).
However, that's a problem in itself - there's no way of having {{null}}/empty
fields sent to Elasticsearch with this processor, while that might actually be
wanted in some circumstances. Some code within PutElasticsearchRecord removes
null/empty fields from Maps (objects) before sending to the
ElasticSearchClientService controller (then on to Elasticsearch) - however,
there's no way to disable this behaviour. The method also doesn't remove empty
Maps (objects) or Lists (arrays), which isn't ideal for Elasticsearch output
either.
I think, therefore, allowing this behaviour to be controlled by the JSON
serialisation within the controller service makes more sense.

> The PutElasticsearchRecord (or the related ES client service) should allow
> for null values to be suppressed (like PutElasticsearchHttpRecord) as it's
> not always desirable to have null values for empty fields (which might be
> present in the schema used to read the data in nifi but not populated).
> Likely this will need changes to the configuration of the ObjectMapper used
> by the ES service depending upon user provided settings.
