Jorge created ARROW-9788:
----------------------------
Summary: Handle naming inconsistencies between SQL, DataFrame API
and struct names
Key: ARROW-9788
URL: https://issues.apache.org/jira/browse/ARROW-9788
Project: Apache Arrow
Issue Type: Improvement
Components: Rust - DataFusion
Reporter: Jorge
Assignee: Andy Grove
Currently, we have naming inconsistencies between the different APIs that make
it a bit confusing. The typical example atm is
`df.where().to_plan?.explain()` shows a "Selection" in the plan when
"Selection" in SQL and many other query languages is a projection, not a filter.
Other examples:
```
name: Selection
SQL: WHERE
DF: filter
```
```
name: Aggregation
SQL: GROUP BY
DF: aggregate
```
```
name: Projection
SQL: SELECT
DF: select,select_columns
```
I suggest that we align them with a common notation, preferably aligned with
other more common query languages.
I am assigning this to you [~andygrove] as you are probably the only person
that can take a decision on this.
