Thanks for your question @jorgecarleitao. > imo it is a bit counter-intuitive to write SELECT MIN(c1) FROM table1 and get MIN(table.c1) as the schema. Are there other engine doing this? Not that I know of for now. There are some other engines' behavior [here](https://github.com/apache/arrow-datafusion/blob/master/docs/specification/output-field-name-semantic.md#function-transformed-columns). This proposal does change a lot. From eliminating all qualifiers to bring all to those composite expressions. > would yield the schema "SUM(table1.c1)" or "SUM(c1)" It will be `SUM(table1.c1)`. The way of interacting with dataframe doesn't change. Only the result field names are different. There is one [example](https://github.com/apache/arrow-datafusion/pull/952/files#diff-1ca1a4d1e2c60e21a139b211b92f05889ae035c2fa9aa87bc878c32f26606fabR262-R291) in `execution/dataframe_impl.rs` -- This is an automated message from the Apache Git Service.
