There are several ways to have an incremental load.
If there is not too much data, you might consider using a tMap which inner joins existing data with all data and then have an output which catches the reject of inner join.
So far, talend CDC feature(Change Data Capture) doesn't support for SAP.
I have the same question: is cdc still not supported for SAP? What I get from this page :
is that it only is available in the paid subscription for Oracle, MySQL, DB2, PostgreSQL, Sybase, MS SQL Server, Informix, Ingres, Teradata, and AS/400.
Can you confirm that this is still the case in the latest version? Is SAP support for CDC expected?
You will get Talend CDC feature in talend subscription solution not open source.
So far, the CDC feature is available for the following databases: AS/400, DB2, Informix, Ingres, MS SQL Server, MySQL, Oracle, PostgreSQL, Sybase and Teradata.
Talend named a Leader.
