    Description

      The Solr 9.0 /export handler has faster sorting (SOLR-15064). This improved export performance will translate to faster joins. It's time now to revisit the Streaming Expression join package and the parallel function to improve the performance of distributed joins. The HashQParserPlugin is key to this and there is an existing ticket to improve this as well (SOLR-15185).

      It's also time to turn the fetch expression into a fully functioning nested loop join.
