Dennis Gove commented on SOLR-9337: ----------------------------------- How does a fetch differ from an innerJoin? I guess it could if it read in a tuple from the source and then looked up its specific fields, but I dunno how performant that'd be. > Add fetch Streaming Expression > ------------------------------ > > Key: SOLR-9337 > URL: https://issues.apache.org/jira/browse/SOLR-9337 > Project: Solr > Issue Type: New Feature > Security Level: Public(Default Security Level.
