Connect to EnterpriseDB Data in as an External Source in Dremio

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

The CData JDBC Driver enables high-speed access to live EnterpriseDB data in Dremio. Once you install the driver, authenticate with EnterpriseDB and gain immediate access to EnterpriseDB data within your data lake. By surfacing EnterpriseDB data using native data types and handling complex filters, aggregations, & other operations automatically, the CData JDBC Driver grants seamless access to EnterpriseDB 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 EnterpriseDB to %DREMIO_HOME%/jars/3rdparty. You can use commands similar to the following:

ARP Connector

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

JDBC Driver for EnterpriseDB

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

Connecting to EnterpriseDB

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

java -jar cdata.jdbc.enterprisedb.jar

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

The following connection properties are required in order to connect to data.

• Server: The host name or IP of the server hosting the EnterpriseDB database.
• Port: The port of the server hosting the EnterpriseDB database.

You can also optionally set the following:

• Database: The default database to connect to when connecting to the EnterpriseDB Server. If this is not set, the user's default database will be used.

Connect Using Standard Authentication

To authenticate using standard authentication, set the following:

• User: The user which will be used to authenticate with the EnterpriseDB server.
• Password: The password which will be used to authenticate with the EnterpriseDB server.

Connect Using SSL Authentication

You can leverage SSL authentication to connect to EnterpriseDB data via a secure session. Configure the following connection properties to connect to data:

• SSLClientCert: Set this to the name of the certificate store for the client certificate. Used in the case of 2-way SSL, where truststore and keystore are kept on both the client and server machines.
• SSLClientCertPassword: If a client certificate store is password-protected, set this value to the store's password.
• SSLClientCertSubject: The subject of the TLS/SSL client certificate. Used to locate the certificate in the store.
• SSLClientCertType: The certificate type of the client store.
• SSLServerCert: The certificate to be accepted from the server.

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:enterprisedb:RTK=5246...;User=postgres;Password=admin;Database=postgres;Server=127.0.0.1;Port=5444

Access EnterpriseDB as an External Source

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

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