Glue Connectors Deployment Guide - Cassandra


The Cassandra Glue Connector for AWS Glue simplifies the process of connecting AWS Glue jobs to extract data from Cassandra. This connector provides comprehensive access to Cassandra data, facilitating cloud ETL processes for operational reporting, data governance, and more.

In this post, we will walk you through a step-by-step configuration to set up Cassandra connector for Glue to Extract, Transform & Load data from Cassandra. You can deploy the Cassandra connector for Glue from the AWS Marketplace.

Let’s start with discussing the prerequisites and then detailing the steps involved.

Versions Available: 1.0.0


The following information should be available handy to start the setup.

You can pass the following options to the connector.

  • host (required) the Maria DB database host IP or domain that is publicly accessible.

  • port (optional, default is 9042) the database port.

  • keyspace (required) the keyspace (schema).

  • datacenter (required) the datacenter (example: us-east-1).

  • username (required) the database user's username.

  • password (required) the database user's password.

  • table (required) the table name you want to pull data, consider the case sensitivity in the table name.

The recommended approach to setting the connector options

Use AWS Secrets Manager can be used to store username, password and other sensitive information related to source connection.


The IAM Role you will be using in the Glue Job should contain the following policies

AWS Glue Service - To run the job.

Amazon EC2 Container Registry - To access AWS Container Registry.

Secrets Manager (optional) - If you use AWS Secrets Manager for connection options.


Using the Cassandra Connector for AWS Glue

Here are the setup steps for configuring the Cassandra Connector:

  • Setup IAM Role for policies and secret AWS Secrets Manager.

  • Setup Cassandra connector and a related connection on Glue Studio console.

  • Create a job.

  • Save and run the job.

Step 1: Setup IAM Role for policies and secret AWS Secrets Manager

Create role and secret:

  • IAM Role for policies as described in prerequisites.

  • Optional - Create secret in AWS Secrets Manager for the connector options described in prerequisites.

Step 2: Setup Cassandra connector and a related connection on Glue Studio console

To set up the Cassandra connector and create a connection for your job:

  • Please subscribe to the product from AWS Marketplace and Activate the Glue connector from AWS Glue Studio

  • Enter your connection name and choose "Create connection and active connector". You can optionally add a description, "Connection access" and "Network options". If you have created an AWS secret with the connector options you can choose your AWS secret from the dropdown under "Connection access".


Step 3: Create a job

To create a job from your connection which is created in the previous step:

  • Choose the connection and "create job".

  • Select your created connection figure on the visual canvas.



  • Add connection options and enter the necessary information.

    • Follow the earlier step (Connector options you need to set) to add the connection options

    • Or you can create an AWS secret with the connector options and attach with the connection as stated in the above step 2.1.

  • Enter the job name, choose IAM Role created in step 1, and other properties in the "Job details" tab, and Choose "Save"


Note: Select language as Scala.

Step 4: Save and run the job

Run the job after filling in all parameters and creating the connector job.


From the above details, you learned how to configure and use Glue connector for Cassandra. Now you don’t need to wait for all the data in your Cassandra to be used for ETL Jobs and maintained on a day-to-day basis to run your Jobs.
