Streaming Data Into Teradata Vantage Using AWS Glue Streaming ETL

Streaming Data Into Teradata Vantage Using AWS Glue Streaming ETL
Many Teradata customers are interested in integrating Teradata Vantage with Amazon Web Services First Party Services. This guide will help you to stream data into Teradata Vantage using AWS Glue Streaming ETL.

The procedure offered in this guide has been implemented and tested by Teradata. However, it is offered on an as-is basis. Amazon does not provide validation of Teradata Vantage using Glue services.

We encourage your feedback. We want to understand what you found useful, and how we can improve this guide. Please send your feedback to Wenjie.Tehan@teradata.com and Shamira.Joshua@teradata.com.

This guide includes content from both Amazon and Teradata product documentation.

This guide was developed in collaboration with Jobin George, Sr. Partner Solutions Architect at AWS, and Vijay Pawar, Sr. Solutions Architect at AWS.

Teradata is an AWS Partner Network (APN) Advanced Technology Partner, specializing in cloud analytics, and has experience using these custom database connectors.

Overview

This guide describes the procedure to stream data into Teradata Vantage on AWS with AWS Glue Streaming ETL jobs and Amazon Kinesis, and visualize the data with Amazon QuickSight.

The following architecture illustrates the flow of data from Amazon Kinesis, through which it is streamed by AWS Glue to Teradata Vantage where it’s analyzed, and finally to Amazon QuickSight, where it’s displayed. In this tutorial we will be using a simple Lambda function to stimulate a streaming source.

About AWS Glue

AWS Glue is a fully managed extract, transform, and load (ETL) service that makes it easy to prepare and load your data for analytics. You can create and run an ETL job with a few clicks in the AWS Management Console.

AWS Glue now supports streaming ETL. This feature makes it easy to set up continuous ingestion pipelines that prepare streaming data on the fly and make it available for analysis in seconds. Streaming ETL jobs in AWS Glue run on the Apache Spark Structured Streaming engine, so customers can use them to enrich, aggregate, and combine streaming data, as well as to run a variety of complex analytics and machine learning operations.

Previously, you had to manually construct and stitch together stream handling and monitoring systems to build streaming data ingestion pipelines. Streaming ETL jobs in AWS Glue leverage AWS Glue’s serverless infrastructure to simplify resource management, optimize cost, and enable you to set up continuous ingestion pipelines without writing code - reducing average implementation time from months to days.

About Amazon Kinesis

Amazon Kinesis Data Streams (KDS) is a massively scalable and durable real-time data streaming service. KDS can continuously capture gigabytes of data per second from hundreds of thousands of sources such as website clickstreams, database event streams, financial transactions, social media feeds, IT logs, and location-tracking events. The data collected is available in milliseconds to enable real-time analytics use cases such as real-time dashboards, real-time anomaly detection, dynamic pricing, and more.
