Connect to Amazon DynamoDB Data in as an External Source in Dremio

The CData JDBC Driver for Amazon DynamoDB implements JDBC Standards and allows various applications, including Dremio, to work with live Amazon DynamoDB data. 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 Amazon DynamoDB data as a part of your enterprise data lake. This article describes how to connect to Amazon DynamoDB data from Dremio as an External Source.

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

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 Amazon DynamoDB to %DREMIO_HOME%/jars/3rdparty. You can use commands similar to the following:

ARP Connector

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

JDBC Driver for Amazon DynamoDB

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

Connecting to Amazon DynamoDB

Amazon DynamoDB will now appear as an External Source option in Dremio. The ARP Connector built uses a JDBC URL to connect to Amazon DynamoDB data. 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 Amazon DynamoDB JDBC Driver. Double-click the JAR file or execute the jar file from the command line.

java -jar cdata.jdbc.amazondynamodb.jar

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

The connection to Amazon DynamoDB is made using your AccessKey, SecretKey, and optionally your Domain and Region. Your AccessKey and SecretKey can be obtained on the security credentials page for your Amazon Web Services account. Your Region will be displayed in the upper left-hand corner when you are logged into DynamoDB.

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:amazondynamodb:RTK=5246...;Access Key=xxx;Secret Key=xxx;Domain=amazonaws.com;Region=OREGON;

Access Amazon DynamoDB as an External Source

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

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