HyukjinKwon opened a new pull request, #46789:
URL: https://github.com/apache/spark/pull/46789
### What changes were proposed in this pull request?
This PR proposes to Implement DataFrameQueryContext in Spark Connect. It
adds two new protobuf messages packed together with `Expression`:
```proto
message Origin {
// (Required) Indicate the origin type.
oneof function {
PythonOrigin python_origin = 1;
}
}
message PythonOrigin {
// (Required) Name of the origin, for example, the name of the function
string fragment = 1;
// (Required) Callsite to show to end users, for example, stacktrace.
string call_site = 2;
}
```
They are set to individual expression messages, and use the information such
as callsite when analysis happens. This resembles Spark SQL implementation.
