    • convertInsert

      protected org.apache.calcite.rel.RelNode convertInsert(org.apache.calcite.sql.SqlInsert call)
      Convert a Druid INSERT or REPLACE statement. The code is the same as the normal conversion, except we don't actually create the final modify node. Druid has its own special way to handle inserts. (This should probably change in some future, but doing so requires changes in the SQL engine and MSQ, which is a bit invasive.)
