Connect to OData Services in as an External Source in Dremio

The CData JDBC Driver for OData implements JDBC Standards and allows various applications, including Dremio, to work with live OData services. Dremio is a data lakehouse platform designed to empower self-service, interactive analytics on the data lake. With the CData JDBC Driver, you can include live OData services as a part of your enterprise data lake. This article describes how to connect to OData services from Dremio as an External Source.

The CData JDBC Driver enables high-speed access to live OData services in Dremio. Once you install the driver, authenticate with OData and gain immediate access to OData services within your data lake. By surfacing OData services using native data types and handling complex filters, aggregations, & other operations automatically, the CData JDBC Driver grants seamless access to OData services.

Build the ARP Connector

To use the CData JDBC Driver in Dremio, you need to build an Advanced Relation Pushdown (ARP) Connector. You can view the source code for the Connector on GitHub or download the ZIP file (GitHub.com) directly. Once you copy or extract the files, run the following command from the root directory of the connector (the directory containing the pom.xml file) to build the connector.

mvn clean install

Once the JAR file for the connector is built (in the target directory), you are ready to copy the ARP connector and JDBC Driver to your Dremio instance.

Installing the Connector and JDBC Driver

Install the ARP Connector to %DREMIO_HOME%/jars/ and the JDBC Driver for OData to %DREMIO_HOME%/jars/3rdparty. You can use commands similar to the following:

ARP Connector

docker cp PATH\TO\dremio-odata-plugin-20.0.0.jar dremio_image_name:/opt/dremio/jars/

JDBC Driver for OData

docker cp PATH\TO\cdata.jdbc.odata.jar dremio_image_name:/opt/dremio/jars/3rdparty/

Connecting to OData

OData will now appear as an External Source option in Dremio. The ARP Connector built uses a JDBC URL to connect to OData services. The JDBC Driver has a built-in connection string designer that you can use (see below).

Built-in Connection String Designer

For assistance in constructing the JDBC URL, use the connection string designer built into the OData JDBC Driver. Double-click the JAR file or execute the jar file from the command line.

java -jar cdata.jdbc.odata.jar

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

The User and Password properties, under the Authentication section, must be set to valid OData user credentials. In addition, you will need to specify a URL to a valid OData server organization root or OData services file.

NOTE: To use the JDBC Driver in Dremio, you will need a license (full or trial) and a Runtime Key (RTK). For more information on obtaining this license (or a trial), contact our sales team.

Add the Runtime Key (RTK) to the JDBC URL. You will end up with a JDBC URL similar to the following:

jdbc:odata:RTK=5246...;URL=http://services.odata.org/V4/Northwind/Northwind.svc;UseIdUrl=True;OData Version=4.0;Data Format=ATOM;

Access OData as an External Source

To add OData as an External Source, click to add a new source and select OData. Copy the JDBC URL and paste it into the New OData Source wizard.

Save the connection and you are ready to query live OData services in Dremio, easily incorporating OData services into your data lake.
