**Need help, i am not sure if i do the right direction for this ticket:** I am still debugging my draft PR, if folks can cooperate, feel free to add a fix to my PR because it will meet more corner cases i believe, and i am still not fixing the existing error: https://github.com/apache/datafusion/pull/15532 More problems need to be fixed based on my PR, for example: - [ ] It seems, simplify_expressions will change the sum(a + b) => sum(a) + sum(b), so the error happens: ```rust logical_plan after simplify_expressions 01)Projection: sum(simple_explain_test.a + simple_explain_test.b) 02)--Aggregate: groupBy=[[]], aggr=[[sum(simple_explain_test.a) + sum(simple_explain_test.b) AS sum(simple_explain_test.a + simple_explain_test.b)]] 03)----TableScan: simple_explain_test ``` ```rust logical_plan 01)Aggregate: groupBy=[[]], aggr=[[sum(simple_explain_test.a) + sum(simple_explain_test.b) AS sum(simple_explain_test.a + simple_explain_test.b)]] 02)--TableScan: simple_explain_test projection=[a, b] physical_plan_error 01)Internal error: Invalid aggregate expression 'BinaryExpr(BinaryExpr { left: AggregateFunction(AggregateFunction { func: AggregateUDF { inner: Sum { signature: Signature { type_signature: UserDefined, volatility: Immutable } } }, params: AggregateFunctionParams { args: [Column(Column { relation: Some(Bare { table: "simple_explain_test" }), name: "a" })], distinct: false, filter: None, order_by: None, null_treatment: None } }), op: Plus, right: AggregateFunction(AggregateFunction { func: AggregateUDF { inner: Sum { signature: Signature { type_signature: UserDefined, volatility: Immutable } } }, params: AggregateFunctionParams { args: [Column(Column { relation: Some(Bare { table: "simple_explain_test" }), name: "b" })], distinct: false, filter: None, order_by: None, null_treatment: None } }) })'. 02)This was likely caused by a bug in DataFusion's code and we would welcome that you file an bug report in our issue tracker ``` - [ ] Some unit tests are failing, need to investigate. - [ ] Need to check if the datatype changes, it is still correct for the rewrite. - [ ] etc -- This is an automated message from the Apache Git Service.
