After [CALCITE-2291|https://issues.apache.org/jira/browse/CALCITE-2291], specifically, [this line|https://github.com/apache/calcite/blob/7088dc7261d294b7c6d5c9f4463435e95f0b9c15/core/src/main/java/org/apache/calcite/sql2rel/SqlToRelConverter.java#L1952] causes volcano planner to fail to find the best plan for query
