ABAP CDS Views join performance

Hi,

I had a question regarding the performance of ABAP CDS views (or Open SQL for that matter).

If the tables in my join condition have large number of columns, but select_list and join conditions contain only few columns out of these, does this have an effect on performance. For example, if my left table of join has multiple columns which are not used in join condition or select list, will this be slower than the scenario, when the left table has less columns.

Example:-

... from tab1

      join

        tab2

          join

            tab3 on tab2.id = tab3.id

                 on tab1.id = tab2.id ...

Does the number of columns in tab1 affect performance, if the fields for join and select list remain same.

Thanks and Regards,
