danny0405 edited a comment 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 their rowType and digest are all the same with each other, for row type equivalence, we mean the field names are also need to be the same, should we sync this rule for MaterializedView ?
