How ADBC connection is benefits by using SAP HANA as secondary database ?

Hi,

I have one more important question.

How ADBC connection is benefits by using SAP HANA as secondary database in terms of performance wise for the access of data from HANA database as a secondary database.

I have 2 options and which is better for the good performance for accessing the data-

1 .  In ABAP Reports in the SELECT statements by using CONNECTION (“HDB”) will this improve the
     performance.
      e.g : select * from BSEG into TABLE IT_TAB CONNECTION (“HDB”).

2. Will Create the Stored procedure in HANA studio and Call
   from ABAP as below by using NATIVE SQL–

     EXEC SQL

      SET CONNECTION (‘HDB’).

     ENDEXEC.

    EXEC SQL.

      EXECUTE PROCEDURE proc (IN    p_in1                       
                             OUT   p_out1   OUT   p_out2 )

   ENDEXEC.

Regards,
Pravin
