-------------------------------------------------------------
For the original mapping take a look at SolrStream, particularly the
{code}mapFields(...){code} function and where it is called from.
It might make sense to require a SelectStream as the inner stream so that one
can select the fields they want to insert. Or perhaps supporting a way to
select fields as part of this stream's expression and it can internally use a
SelectStream to implement that feature.

> Add UpdateStream to Streaming API and Streaming Expression
> ----------------------------------------------------------
>
> Key: SOLR-7535
> URL: https://issues.apache.org/jira/browse/SOLR-7535
> Project: Solr
> Issue Type: New Feature
> Components: clients - java, SolrJ
> Reporter: Joel Bernstein
> Priority: Minor
>
> The ticket adds an UpdateStream implementation to the Streaming API and
> streaming expressions. The UpdateStream will wrap a TupleStream and send the
> Tuples it reads to a SolrCloud collection to be indexed.
> This will allow users to pull data from different Solr Cloud collections,
> merge and transform the streams and send the transformed data to another Solr
> Cloud collection.
