danny0405 commented on issue #1310: [CALCITE-3113] Equivalent MutableAggregates with different row types should match with each other. URL: https://github.com/apache/calcite/pull/1310#issuecomment-509921250 > What do we do elsewhere (e.g. in RelOptRules)? Do we check whether row-types are the same modulo field names? My concern is the same, in `RelOptPlanner`, we think 2 rels are equivalent only there rowType and digest are all the same with each other, for row type equals, we mean the field names are also need to be the same, should we sync this rule for MaterializedView ?
