--------------------------------
> Implement Query and Scroll processors for ElasticSearch
> -------------------------------------------------------
>
> Key: NIFI-2417
> URL: https://issues.apache.org/jira/browse/NIFI-2417
> Project: Apache NiFi
> Issue Type: New Feature
> Components: Extensions
> Affects Versions: 1.0.0
> Reporter: Joseph Gresock
> Assignee: Joseph Gresock
> Priority: Minor
> Fix For: 1.1.0
>
>
> FetchElasticsearchHttp allows users to select a single document from
> Elasticsearch in NiFi, but there is no way to run a query to retrieve
> multiple documents.
> We should add a QueryElasticsearchHttp processor for running a query and
> returning a flow file per result, for small result sets. This should allow
> both input and non-input execution.
> A separate ScrollElasticsearchHttp processor would also be useful for
> scrolling through a huge result set. This should use the state manager to
> maintain the scroll_id value, and use this as input to the next scroll page.
> As a result, this processor should not allow flow file input, but should
> retrieve one page per run.
