Basic Quetions about Built-in func Parallel & Server Job

Post by anajitKS »

When we use the built-in functions in Transformer in Server job or Parallel job,
do they get included in the main program after compilation ?

I have same question about the user defined functions.

Built-in functions are included in the process that runs the Transformer stage (DSD.StageRun for server jobs, a player process executing the transform operator for parallel jobs).

User-defined routines are external, and called by the process executing the Transformer stage. For parallel jobs there must also exist an "interlude" that specifies the expected arguments and return value.

Server jobs can also call external functions through a mechanism called the General Call Interface (GCI). Again there must exist an "interlude" that specifies the expected arguments and return value.
