There's an assertAllTransferred that can be used here to simply things.
> Add FetchSolr processor
> -----------------------
>
> Key: NIFI-4516
> URL: https://issues.apache.org/jira/browse/NIFI-4516
> Project: Apache NiFi
> Issue Type: Improvement
> Components: Extensions
> Reporter: Johannes Peter
> Assignee: Johannes Peter
> Priority: Major
> Labels: features
>
> The processor shall be capable
> * to query Solr within a workflow,
> * to make use of standard functionalities of Solr such as faceting,
> highlighting, result grouping, etc.,
> * to make use of NiFis expression language to build Solr queries,
> * to handle results as records.
