[jira] [Created] (SOLR-10402) Add extract Streaming Expression

Joel Bernstein created SOLR-10402:
-------------------------------------

             Summary: Add extract Streaming Expression 
                 Key: SOLR-10402
                 URL: https://issues.apache.org/jira/browse/SOLR-10402
             Project: Solr
          Issue Type: New Feature
      Security Level: Public (Default Security Level. Issues are Public)
            Reporter: Joel Bernstein


The extract Streaming Expression is designed to offload extraction services, such as Apache Tika, to worker nodes. This will allow a separate Solr Cloud cluster to perform the heavy weight extractions and then send the results to a Solr Cloud collection for indexing. 

By leveraging the Solr parallel executor framework (http://joelsolr.blogspot.com/2017/01/deploying-solrs-new-parallel-executor.html) and worker nodes we should be able deploy massively scalable extraction services.
