Smart Data Access vs CSV File input

Hi ,

We are having both SQL Server and HANA databases. We move data regularly from SQL server to HANA. We are thinking about the following approaches.

1. Create a batch script to export data from SQL Server tables ->transfer it through FTP to HANA server -> import CSV files using HANA

IMPORT FROM CSV FILE ‘/home/hanauser/TABLE_EXPORTs/table.csv' INTO "MYTABLE"

WITH

RECORD DELIMITED BY '\n'

FIELD DELIMITED BY ',';

     2. Use an ETL tool like Informatica to do the data movement.

     3. Use Smart Data Access->create a SQL Server remote source-> create virtual tables -> write a procedure to move data.

We are trying to reduce the time taken to do this. Data size is not huge ,1000 rows at any time  but with 100-150 columns

  Smart Access seems to be the easiest. How good is the performance?

Which approach is better and why?
