> Protobuf: Read descriptor file only once at the compile time

>                 Key: SPARK-43530

>             Project: Spark
>          Issue Type: Task
>          Components: Protobuf
>    Affects Versions: 3.5.0
>            Reporter: Raghu Angadi
>            Assignee: Raghu Angadi
>            Priority: Major
>             Fix For: 3.5.0
>
>
> Protobuf functions read from the descriptor file many time (e.g. at each 
> executor). This is unncessary and error prone (e.g. what if the contents 
> change couple of days after the streaming query starts?).
>  
> It only needs to be read once.
