Create a star schema that shows perspectives on Avro facts in real time.

The CData ODBC Driver for Avro is a standard database driver that can integrate real-time access to Avro data into your data warehouse or directly into your reporting tool. This article shows how to bypass the data warehouse and import operational Avro data into Oracle Business Intelligence Enterprise Edition (OBIEE).

See the knowledge base for ODBC integrations with ETL tools like Informatica PowerCenter. For an ETL solution into Oracle Warehouse Builder, use the driver with the Oracle ODBC Gateway to Access Avro Data as a Remote Oracle Database.

Connect to Avro as an ODBC Data Source

If you have not already, first specify connection properties in an ODBC DSN (data source name). This is the last step of the driver installation. You can use the Microsoft ODBC Data Source Administrator to create and configure ODBC DSNs.

Connect to your local Avro file(s) by setting the URI connection property to the location of the Avro file.

When you configure the DSN, you may also want to set the Max Rows connection property. This will limit the number of rows returned, which is especially helpful for improving performance when designing reports and visualizations.

Import Avro Metadata

Follow the steps below to use the OBIEE Client Tools to import Avro metadata into an OBIEE repository. You can then integrate Avro data into your business models.

  1. Open the Administration Tool and click File -> New Repository.

  2. In the Connection Type menu, select ODBC 3.5 and select the CData DSN.
  3. Select the metadata types you want to import under the Relational Sources option and then select Avro tables.
You can now create star schemas based on Avro tables:
