The purpose of this capability is to be able to specify bulk operations. In
ElasticSearch, you can specify the whole range of CRUD operations in a single
bulk operation. That's what this is going for. So you can say "add this, this
and this, delete this, upsert that and delete this thing too" in one push.
It has the potential to be quite useful to teams doing a lot of work with
ElasticSearch because they will not have to segment changes into different
flows, but can create a single flow that is able to take actions to be
performed and bulk deliver them to ES through one pipeline.

> 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.
