Load SAP Business Warehouse Data to a Database Using Embulk

Embulk is an open source bulk data loader. When paired with the CData JDBC Driver for SAP Business Warehouse, Embulk easily loads data from SAP Business Warehouse to any supported destination. In this article, we explain how to use the CData JDBC Driver for SAP Business Warehouse in Embulk to load SAP Business Warehouse data to a MySQL dtabase.

With built-in optimized data processing, the CData JDBC Driver offers unmatched performance for interacting with live SAP Business Warehouse data. When you issue complex SQL queries to SAP Business Warehouse, the driver pushes supported SQL operations, like filters and aggregations, directly to SAP Business Warehouse and utilizes the embedded SQL engine to process unsupported operations client-side (often SQL functions and JOIN operations).

Configure a JDBC Connection to SAP Business Warehouse Data

Before creating a bulk load job in Embulk, note the installation location for the JAR file for the JDBC Driver (typically C:\Program Files\CData\CData JDBC Driver for SAP Business Warehouse\lib).

Embulk supports JDBC connectivity, so you can easily connect to SAP Business Warehouse and execute SQL queries. Before creating a bulk load job, create a JDBC URL for authenticating with SAP Business Warehouse.

To connect to SAP Business Warehouse, set the URL property to a valid SAP Business Warehouse server base URL. The driver must connect to SAP Business Warehouse instances hosted over HTTP with XMLA access.

The driver supports the following authentication schemes via the AuthScheme property:

• None: Anonymous authentication, if available on the server.
• Basic: Set User and Password and set AuthScheme to Basic.
• Kerberos: See the Using Kerberos section of the help documentation for the required Kerberos properties.

By default, the driver attempts to negotiate SSL/TLS by checking the server's certificate against the system's trusted certificate store. To specify another certificate, see the SSLServerCert property for the available formats.

Built-in Connection String Designer

For assistance in constructing the JDBC URL, use the connection string designer built into the SAP Business Warehouse JDBC Driver. Either double-click the JAR file or execute the jar file from the command-line.

java -jar cdata.jdbc.sapbusinesswarehouse.jar

Fill in the connection properties and copy the connection string to the clipboard.

Below is a typical JDBC connection string for SAP Business Warehouse:

jdbc:sapbusinesswarehouse:URL=https://mysapserver:8000;AuthScheme=Basic;User=username;Password=password;

Load SAP Business Warehouse Data in Embulk

After installing the CData JDBC Driver and creating a JDBC connection string, install the required Embulk plugins.

Install Embulk Input & Output Plugins

1. Install the JDBC Input Plugin in Embulk.
   https://github.com/embulk/embulk-input-jdbc/tree/master/embulk-input-jdbc

embulk gem install embulk-input-jdbc

2. In this article, we use MySQL as the destination database. You can also choose SQL Server, PostgreSQL, or Google BigQuery as the destination using the output Plugins.
   https://github.com/embulk/embulk-output-jdbc/tree/master/embulk-output-mysql

   embulk gem install embulk-output-mysql
   

With the input and output plugins installed, we are ready to load SAP Business Warehouse data into MySQL using Embulk.

Create a Job to Load SAP Business Warehouse Data

Start by creating a config file in Embulk, using a name like sapbusinesswarehouse-mysql.yml.

1. For the input plugin options, use the CData JDBC Driver for SAP Business Warehouse, including the path to the driver JAR file, the driver class (e.g. cdata.jdbc.sapbusinesswarehouse.SAPBusinessWarehouseDriver), and the JDBC URL from above
2. For the output plugin options, use the values and credentials for the MySQL database

Sample Config File (sapbusinesswarehouse-mysql.yml)

in:
	type: jdbc
	driver_path: C:\Program Files\CData[product_name] 20xx\lib\cdata.jdbc.sapbusinesswarehouse.jar
	driver_class: cdata.jdbc.sapbusinesswarehouse.SAPBusinessWarehouseDriver
	url: jdbc:sapbusinesswarehouse:URL=https://mysapserver:8000;AuthScheme=Basic;User=username;Password=password;
	table: "Sales"
out: 
	type: mysql
	host: localhost
	database: DatabaseName
	user: UserId
	password: UserPassword
	table: "Sales"
	mode: insert

After creating the file, run the Embulk job.

embulk run sapbusinesswarehouse-mysql.yml

After running the the Embulk job, find the Salesforce data in the MySQL table.

Load Filtered SAP Business Warehouse Data

In addition to loading data directly from a table, you can use a custom SQL query to have more granular control of the data loaded. You can also perform increment loads by setting a last updated column in a SQL WHERE clause in the query field.

in:
	type: jdbc
	driver_path: C:\Program Files\CData[product_name] 20xx\lib\cdata.jdbc.sapbusinesswarehouse.jar
	driver_class: cdata.jdbc.sapbusinesswarehouse.SAPBusinessWarehouseDriver
	url: jdbc:sapbusinesswarehouse:URL=https://mysapserver:8000;AuthScheme=Basic;User=username;Password=password;
	query: "SELECT CustomerCount, City FROM Sales WHERE [RecordId] = 1"
out: 
	type: mysql
	host: localhost
	database: DatabaseName
	user: UserId
	password: UserPassword
	table: "Sales"
	mode: insert
