             Summary: JdbcRules JOIN_FACTORY, AGGREGATE_FACTORY, 
SET_OP_FACTORY, ... create relations with wrong convention
                 Key: CALCITE-4320
                 URL: https://issues.apache.org/jira/browse/CALCITE-4320
             Project: Calcite
          Issue Type: Sub-task
          Components: core
    Affects Versions: 1.26.0
            Reporter: Vladimir Sitnikov


{code:java}
  static final RelFactories.JoinFactory JOIN_FACTORY =
      (left, right, hints, condition, variablesSet, joinType, semiJoinDone) -> {
        final RelOptCluster cluster = left.getCluster();
        final RelTraitSet traitSet = cluster.traitSetOf(left.getConvention());
        try {
          return new JdbcJoin(cluster, traitSet, left, right, condition,
              variablesSet, joinType);
{code}

In practice, JdbcJoin should use JdbcConvention rather than 
{{cluster.traitSetOf(left.getConvention());}}

I wonder if RelFactories in JdbcRules are dead code.
