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

The SAP HANA Connector loads data into Incorta from SAP HANA databases. The connector uses a sqljdbc42.jar file that is included with the Incorta customer release distribution. You can find the JAR file in the following directory: {path to IncortaNode}/runtime/lib

The SAP HANA connector supports the following Incorta specific functionality:

FeatureSupported
Chunking
Data Agent
Encryption at Ingest
Incremental Load
Multi-Source
OAuth
Performance Optimized
Remote
Single-Source
Spark Extraction
Webhook Callbacks

Steps to connect SAP HANA and Incorta

To connect SAP HANA and Incorta, here are the high level steps, tools, and procedures:

Create an external data source

Here are the steps to create a external data source with the SAP HANA connector:

  • Sign in to the Incorta Direct Data Platform.
  • In the Navigation bar, select Data.
  • In the Action bar, select + NewAdd Data Source.
  • In the Choose a Data Source dialog, in Database, select SAP Hana.
  • In the New Data Source dialog, specify the applicable connector properties.
  • To test, select Test Connection.
  • Select Ok to save your changes.

SAP HANA connector properties

Here are the properties for the SAP HANA connector:

PropertyControlDescription
Data Source Nametext boxEnter the name of the data source
Usernametext boxEnter the database username
Passwordtext boxEnter the database password
Connection Pooltext boxEnter the connection pool. The default is 30.
Connection Stringtext boxEnter the connection string for the SAP JDBC driver. The format is: jdbc:sap://<HOST>:<PORT>/<DB>
Connection Propertiestext boxThere are not currently any connection properties for the SAP HANA connector.
Use Data AgenttoggleEnable using a data agent to securely ingest data from an external data source that is behind a firewall.
For more information, please review Tools → Data Agent and Tools → Data Manager.
Data Agentdrop down listEnable 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. A CMC Administrator must enable and configure an Incorta cluster to support the use of Data Agents. Only a Tenant Administrator (Super User) or user that belongs to a group with the SuperRole role for a given tenant can create a data agent that connects to a data agent service. To learn more, see Concepts → Data Agent and Tools → Data Agent.

  • In (3) Finalize, in the Schema Wizard footer, select Create Schema.

Create a schema with the Schema Designer

Here are the steps to create an SAP HANA schema using the Schema Designer:

  • Sign in to the Incorta Direct Data Platform.
  • In the Navigation bar, select Schema.
  • In the Action bar, select + New → Create Schema.
  • In Name, specify the schema name, and select Save.
  • In Start adding tables to your schema, select SQL Database.
  • In the Data Source dialog, specify the SAP HANA table data source properties.
  • Select Add.
  • In the Table Editor, in the Table Summary section, enter the table name.
  • To save your changes, select Done in the Action bar.

SAP HANA table data source properties

For a schema table in Incorta, you can define the following SAP HANA specific data source properties as follows:

PropertyControlDescription
Typedrop down listDefault is SQL Database
Data Sourcedrop down listSelect the SAP HANA external data source
IncrementaltoggleEnable the incremental load configuration for the schema table. See the simple incremental load example configuration below.
Fetch Sizetext boxUsed for performance improvement, fetch size defines the number of records that will be retrieved from the database in each batch until all records are retrieved. The default is 5000.
Querytext boxEnter the SQL query to retrieve data from the SAP HANA database
Update Querytext boxEnable Incremental to configure this property. Enter the SQL query to retrieve data updates from the SAP HANA database.
Incremental Field Typedrop down listEnable Incremental to configure this property. Select the format of the table date column:
  ●  TImestamp
  ●  Unix Epoch (seconds)
  ●  Unix Epoch (milliseconds)
Chunking Methoddrop down listChunking methods allow for parallel extraction of large tables. The default is No Chunking. There are two chunking methods:
  ●   By Size of Chunking (Single Table)
  ●   By Date/Timestamp
Chunk Sizetext boxSelect By Size of Chunking for the Chunking Method to set this property. Enter the number of records to extract in each chunk in relation to the Fetch Size. The default is 3 times the Fetch Size.
Order Columndrop down listSelect By Size of Chunking for the Chunking Method to set this property. Select a column in the source table you want to order by before chunking. It's typically an ID column and it must be numeric.
Upper Bound for Order Columntext boxOptional. Enter the maximum value for the order column.
Lower Bound for Order Columntext boxOptional. Enter the minimum value for the order column.
Order Column [Date/Timestamp]drop down listSelect By Date/Timestamp for the Chunking Method to set this property. Select a column in the source table you want to order by before chunking. It should be a Date/Timestamp column.
Chunk Perioddrop down listSelect the chunk period that will be used in dividing chunks:
  ●   Daily
  ●   Weekly (default)
  ●  Monthly
  ●  Yearly
  ●  Custom
Number of daystext boxSelect Custom for the Chunk Period to set this property. Enter the chunking period in days
CallbacktoggleEnable post extraction callback, that is, enable callback on the data source data set(s) by invoking a certain callback URL with parameters containing details about the load job
Callback URLtext boxEnable Callback to configure this property. Specify the callback URL.

View the schema diagram with the Schema Diagram Viewer

Here are the steps to view the schema diagram using the Schema Diagram Viewer:

  • Sign in to the Incorta Direct Data Platform.
  • In the Navigation bar, select Schema.
  • In the list of schemas, select the SAP HANA schema.
  • In the Schema Designer, in the Action bar, select Diagram.

Load the schema

Here are the steps to perform a Full Load of the SAP HANA schema using the Schema Designer:

  • Sign in to the Incorta Direct Data Platform.
  • In the Navigation bar, select Schema.
  • In the list of schemas, select the SAP HANA schema.
  • In the Schema Designer, in the Action bar, select LoadFull Load.
  • To review the load status, in Last Load Status, select the date.

Explore the schema

With the full load of the SAP HANA schema complete, you can use the Analyzer to explore the schema, create your first insight, and save the insight to a new dashboard.

To open the Analyzer from the schema, follow these steps:

  • In the Navigation bar, select Schema.
  • In the Schema Manager, in the List view, select the SAP HANA schema.
  • In the Schema Designer, in the Action bar, select Explore Data.

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:

  • Incremental is enabled
  • Query contains SELECT * FROM invoices
  • Update contains SELECT * FROM invoices WHERE ModifiedOn > ?
  • Incremental Field Type = Timestamp
Note

? is a variable in the update query that contains the last schema refresh date.
