Compiled C++ UDF Operator
Category: Productivity Enhancement / Innovation
I want to build a Compiled C++ UDF operator for Texera. The idea is to let
users write small performance-critical UDFs in C++ directly inside a workflow,
compile them from the UI, and run them on incoming data.
This would be useful when Python UDFs are easy to write but too slow for
CPU-heavy tasks like numeric transformations, feature extraction, custom
parsing, or scientific preprocessing.
MVP:
- Select input columns
- Write a simple C++ function
- Compile from the UI
- Show compiler errors in the editor
- Run the compiled function as a workflow operator
- Produce one output column
Example:
double process(double age, double income) {
return income / (age + 1.0);
}
