liukun4515 opened a new issue, #10630:
URL: https://github.com/apache/datafusion/issues/10630
### Describe the bug
In the definition of `AggregateExec`, we have the `limit` argument to
optimize the agg operation.
```
pub struct AggregateExec {
.....
/// Set if the output of this aggregation is truncated by a upstream
sort/limit clause
limit: Option<usize>,
.....
}
```
But it is not added in the .proto file, when we use the proto to ser/deser
the agg physical node, the `limit` will lost.
### To Reproduce
_No response_
### Expected behavior
_No response_
### Additional context
add limit option in the proto file, and add implementation for the `limit`
arg in the to_proto and from_proto
