Description

The Programs class has a static method standard() used by the default Calcite driver. So far Calcite-Phoenix is using the same sql prepare logic with some slight customization, like plugging in a set of its own rules. The static standard(), though, does not work properly for Phoenix since some sub-programs it returns are initiated with the default RelMetadataProvider while Phoenix needs to plug-in its own, otherwise it just could not work.

  /** Program that converts filters and projects to {@link Calc}s. */
  public static final Program CALC_PROGRAM =
      hep(CALC_RULES, true, new DefaultRelMetadataProvider());

  /** Program that expands sub-queries. */
  public static final Program SUB_QUERY_PROGRAM =
      hep(
          ImmutableList.of((RelOptRule) SubQueryRemoveRule.FILTER,
              SubQueryRemoveRule.PROJECT,
              SubQueryRemoveRule.JOIN), true, new DefaultRelMetadataProvider());
