[jira] [Created] (SOLR-13306) Add a request parameter to execute a streaming expression locally

Gus Heck created SOLR-13306:
-------------------------------

             Summary: Add a request parameter to execute a streaming expression locally
                 Key: SOLR-13306
                 URL: https://issues.apache.org/jira/browse/SOLR-13306
             Project: Solr
          Issue Type: Improvement
      Security Level: Public (Default Security Level. Issues are Public)
          Components: streaming expressions
    Affects Versions: 8.0
            Reporter: Gus Heck
            Assignee: Gus Heck


In some cases it is known (due to routing configuration) that all documents required for a streaming expression are co-located on the same server. In this case it is inefficient to send JSON over the wire, and it would be more efficient to issue the same expression to N servers, thereby saving transport and merge costs. Details, Patch and example to follow
