Integrate Cassandra Data in Your Informatica Cloud Instance

Use the CData JDBC Driver for Cassandra with the Informatica Cloud Secure Agent to access live Cassandra data from Informatica Cloud.

Informatica Cloud allows you to perform extract, transform, and load (ETL) tasks in the cloud. With the Cloud Secure Agent and the CData JDBC Driver for Cassandra, you get live access to Cassandra data, directly within Informatica Cloud. In this article, we will walk through downloading and registering the Cloud Secure Agent, connecting to Cassandra through the JDBC Driver and generating a mapping that can be used in any Informatica Cloud process.

Informatica Cloud Secure Agent

To work with the Cassandra data through the JDBC Driver, install the Cloud Secure Agent.

  1. Navigate to the Administrator page in Informatica Cloud
  2. Select the Runtime Environments tab
  3. Click "Download Secure Agent"
  4. Make note of the Install Token
  5. Run the installer on the client machine and register the Cloud Secure Agent with your username and install token

NOTE: It may take some time for all of the Cloud Secure Agent services to get up and running.

Connecting to the Cassandra JDBC Driver

With the Cloud Secure Agent installed and running, you are ready to connect to Cassandra through the JDBC Driver. Start by clicking the Connections tab and clicking New Connection. Fill in the following properties for the connection:

  • Connection Name: Name your connection (i.e.: CData Cassandra Connection)
  • Type: Select "JDBC_IC (Informatica Cloud)"
  • Runtime Environment: Select the runtime environment where you installed the Cloud Secure Agent
  • JDBC Connection URL: Set this to the JDBC URL for Cassandra. Your URL will look similar to the following:

    jdbc:cassandra:Database=MyCassandraDB;Port=7000;Server=127.0.0.1;

    Set the Server, Port, and Database connection properties to connect to Cassandra. Additionally, to use internal authentication set the User and Password connection properties.

    Built-In Connection String Designer

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

    java -jar cdata.jdbc.cassandra.jar

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

  • JDBC Jar Directory: Set this to the lib folder in the installation location for the JDBC Driver (on Windows, typically C:\Program Files\CData\CData JDBC Driver for Cassandra\)
  • Driver Class: Set this to cdata.jdbc.cassandra.CassandraDriver
  • Username: Set this to a placeholder value (since Cassandra does not require a username)
  • Password: Set this to a placeholder value (since Cassandra does not require a password)

Create a Mapping for Cassandra Data

With the connection to Cassandra configured, we can now access Cassandra data in any Informatica process. The steps below walk through creating a mapping for Cassandra to another data target.

  1. Navigate to the Data Integration page
  2. Click New.. and select Mapping from the Mappings tab
  3. Click the Source Object and in the Source tab, select the Connection and set the Source Type
  4. Click "Select" to choose the table to map
  5. In the Fields tab, select the fields from the Cassandra table to map
  6. Click the Target object and configure the Target source, table and fields. In the Field Mapping tab, map the source fields to the target fields.

With the mapping configured, you are ready to start integrating live Cassandra data with any of the supported connections in Informatica Cloud. Download a free, 30-day trial of the CData JDBC Driver for Cassandra and start working with your live Cassandra data in Informatica Cloud today.
