[jira] [Created] (SOLR-10516) Add eval() Streaming Expression

Joel Bernstein created SOLR-10516:
-------------------------------------

             Summary: Add eval() Streaming Expression
                 Key: SOLR-10516
                 URL: https://issues.apache.org/jira/browse/SOLR-10516
             Project: Solr
          Issue Type: New Feature
      Security Level: Public (Default Security Level. Issues are Public)
            Reporter: Joel Bernstein


The eval() Streaming Expression reads a single tuple from an underlying stream and looks in the expr_s field for an expression to compile and run. eval emits the tuples from expression that it compiles. 

This allows streaming expressions to write streaming expressions and have them evaluated in the same.
