    Description

      Because getPredicates(RelSubset r, RelMetadataQuery mq) returns null by default, some rules will not work in volcanoPlanner. Such as SortRemoveConstantKeysRule, UnionPullUpConstantsRule, ExchangeRemoveConstantKeysRule, AggregateJoinTransposeRule, ReduceExpressionsRule, etc. 

      public RelOptPredicateList getPredicates(RelSubset r,
    RelMetadataQuery mq) {
  if (!Bug.CALCITE_1048_FIXED) {
    return RelOptPredicateList.EMPTY;
  } 
}
