The author created a custom dlt integration to connect SAP HANA with Snowflake, allowing for the transfer of data between these two systems. This was achieved by leveraging dlt's SQL source feature and installing additional packages to handle SAP-specific requirements. The integration enables users to load data from SAP HANA into Snowflake, which is cloud-agnostic and can be run in various environments. The author highlights that this connector can also be used with other tools like dbt and airflow, making it a valuable addition to an SAP workflow. Further development plans include creating a verified source for SAP HANA and exploring the possibility of connecting SAP S/4 HANA with Snowflake.
