[PR] Convert built-in row_number to user-defined window function [datafusion]
jcsherin opened a new pull request, #12030:
URL: https://github.com/apache/datafusion/pull/12030
## Which issue does this PR close?
<!--
We generally require a GitHub issue to be filed for all bug fixes and enhancements and this helps us generate change logs for our releases. You can link an issue to this PR using the GitHub syntax. For example `Closes #123` indicates that this PR will close issue #123.
-->
Closes #12029.
## Rationale for this change
<!--
Why are you proposing this change? If this is already explained clearly in the issue then this section is not needed.
Explaining clearly why changes are proposed helps reviewers understand your changes and offer better suggestions for fixes.
-->
Same as described in #8709.
## What changes are included in this PR?
<!--
There is no need to duplicate the description in the issue here but it is sometimes worth providing a summary of the individual changes in this PR.
-->
1. Adds new crate `datafusion-functions-window`.
2. Converts `BuiltinWindowFunction::RowNumber` to user-defined window function.
3. Extends `WindowUDFImpl` with two additional methods.
4. Export a fluent-style API for creating `row_number` expressions.
5. Implements `BuiltinWindowExpr::get_result_ordering` for `WindowUDFExpr` which is necessary for updating ordering equivalences.
## Are these changes tested?
<!--
We typically require tests for all PRs in order to:
1. Prevent the code from being accidentally broken by subsequent changes
7. Serve as another way to document the expected behavior of the code
If tests are not included in your PR, please explain why (for example, are they covered by existing tests)?
-->
1. Adds logical plan round trip test.
2. Updates existing unit tests in `row_number` to use the new API.
3. Updates explain output in sqllogictests to match lowercase `row_number`.
## Are there any user-facing changes?
<!--
If there are user-facing changes then we may require documentation to be updated before approving the PR.
-->
<!--
If there are any breaking changes to public APIs, please add the `api change` label.
-->
Yes.

Review Comment:
This diff is bit large and therefore its not highlighting the words/phrases. The change here is from uppercase `ROW_NUMBER` to lowercase `row_number`.

Review Comment:
The proto enum requires the first value to be zero. See: https://protobuf.dev/programming-guides/dos-donts/#unspecified-enum
Leaving the older value commented out instead of removing it so we know that it was `ROW_NUMBER`. This will anyways be removed once all the other built-ins are moved.

Fine to me. I would be nice to have it includes in the same release to avoid breaking change

Review Comment:
This is why `nullable` method was added to `WindowUDFImpl` so that the user-defined window function can customize nullability of column values.

Review Comment:
Instead of return_type + nullable. I think `field` is a better choice. Given windowudf is pretty new so not widely used yet. It would be nice to have `field(&self, args: FieldArgs) -> Result<Field>`
```rust
FieldArgs {
arg_type: &[DataType]
schema: Schema // for nullable
}
```
It is too late for AggregateUDF and ScalarUDF :(

Forgot what I said about `FieldArgs`, if there are only two args at the end, it might be overkill.

Review Comment:
BTW I don't think `row_number()` takes arguments -- I removed the argument in https://github.com/apache/datafusion/pull/12043
This is the previous row_number implementation here https://github.com/apache/datafusion/pull/12030/files#diff-790fda7313189b10bd29f89102416b93f5708ab88fdd5c89733758e1ed2aafadL22
```rust
/// Create an expression to represent the `row_number` window function
pub fn row_number() -> Expr {
Expr::WindowFunction(WindowFunction::new(
BuiltInWindowFunction::RowNumber,
vec![],
))
}

Review Comment:
I think this makes sense.
All the existing built-in window functions define nullable within the `BuiltInWindowFunctionExpr::field` implementation.
Therefore we can define field like this (without `FieldArgs` struct):
```rust
fn field(&self, arg_types: &[DataType]) -> Result<Field>`
```
This will also eliminate `data_type` field from `WindowUDFExpr` :
https://github.com/apache/datafusion/blob/2a16704db7af0045d465cda39b90d1a17e68dbe8/datafusion/physical-plan/src/windows/mod.rs#L342-L351
Then the `field` method implementation:
https://github.com/apache/datafusion/blob/2a16704db7af0045d465cda39b90d1a17e68dbe8/datafusion/physical-plan/src/windows/mod.rs#L353-L361
Will instead be this:
```rust
impl BuiltInWindowFunctionExpr for WindowUDFExpr {
fn field(&self) -> Result<Field> { self.fun.field() }
}
```

Same here as well. Change is from uppercase ROW_NUMBER to lowercase row_number.

The user-defined window function can specify its result ordering which will be used for updating ordering equivalences.

Review Comment:
Instead of return_type + nullable. I think `field` is a better choice. Given windowudf is pretty new so not widely used yet (?). It would be nice to have `field(&self, args: FieldArgs) -> Result<Field>`
```rust
FieldArgs {
arg_type: &[DataType]
schema: Schema // for nullable
}
```
It is too late for AggregateUDF and ScalarUDF :(
