[jira] [Comment Edited] (SOLR-7535) Add UpdateStream to Streaming
API and Streaming Expression
[ https://issues.apache.org/jira/browse/SOLR-7535?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15069053#comment-15069053 ]

-------------------------------------------------------------
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.

> 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.
