About SAP HANA

SAP HANA is a high-performance in-memory database that accelerates data-driven, real-time decision-making and actions, and supports all workloads with the broadest advanced analytics on multi-model data, on premises and in the cloud.

SAP HANA Connector Updates

This section is to explore the updates in the newer versions of the SAP HANA connector available on the Incorta connectors marketplace.

In order to get the newer version of the connector, please update the connector using the marketplace.

Version	Updates
2.2.0.2	A new extra option, sql.chunks.limit, is now available to specify the maximum number of chunks that can be created by a data set when chunking is enabled. The default is 100, and the maximum is 300. If you specify a limit that exceeds 300, the connector resets it to 300.

Recommendation

Keep your connector up-to-date with the latest connector version released to get all introduced fixes and enhancements.

SAP HANA Connector

Data Agent	drop down list	Enable Use Data Agent to configure this property. Select from the data agents created in the tenant, if any.

Important: Data Agent

A data agent is a service that runs on a remote host. It is also a data agent object in the Data Manager for a given tenant. An authentication file shared between the data agent object and the data agent service enables an authorized connection without using a VPN or SSH tunnel. With a data agent, you can securely extract data from one or more databases behind a firewall to an Incorta cluster. Your Incorta cluster can reside on-premises or in the cloud.

You must have the Incorta cluster enabled and configured to support the use of Data Agents. To learn more, see Concepts → Data Agent and Tools → Data Agent.

Additional Considerations

Below is a simple incremental load configuration example of how you would complete the related data source properties if you enable the Incremental property for the SAP HANA schema table.

Incremental Load Example

The Schema Designer is used to create a table for invoices, and is to be refreshed with invoice updates. In order to load the table incrementally with updates, the invoice table must contain a column of the type date or timestamp. The name of the date column is ModifiedOn, and the format of this column is Timestamp.

Here are the data source property values for this scenario:
