Can't remember if I made the comment here or in another PR, but you could
always add these properties in the constructor or static block so the list only
gets created once. I don't think it creates a memory leak here, so I guess this
is just a style thing
> Create new put processors that use the ElasticSearch client service

> Key: NIFI-5248
> URL: https://issues.apache.org/jira/browse/NIFI-5248
> Project: Apache NiFi
> Issue Type: New Feature
> Reporter: Mike Thomsen
> Assignee: Mike Thomsen
> Priority: Major
>
> Two new processors:
> * PutElasticsearchJson - put raw JSON.
> * PutElasticsearchRecord - put records.
> Both of them should support the general bulk load API and be able to do
> things like insert into multiple indexes from one payload.
