Seamless Integration Unleashed: Amazon Aurora MySQL Zero-ETL with Amazon Redshift

Feature IMG

In a groundbreaking move, Amazon Web Services (AWS) has officially announced the general availability of Amazon Aurora MySQL zero-ETL integration with Amazon Redshift. This game-changing development promises to revolutionize data integration processes, making them more efficient and streamlined than ever before.

Zero-ETL Unleashed: A Paradigm Shift

The introduction of Amazon Aurora MySQL zero-ETL integration with Amazon Redshift marks a significant leap forward in the world of data management. ETL (Extract, Transform, Load) processes have long been a cornerstone of data integration, but the zero-ETL approach takes simplicity and efficiency to new heights.

Traditionally, ETL processes have been a necessary step in the data integration journey. They often involve complex transformations and manipulations, introducing potential bottlenecks and points of failure. With the advent of zero-ETL, these barriers are dismantled, offering users a direct and seamless connection between Amazon Aurora MySQL and Amazon Redshift.

Zero ETL

This zero-ETL integration between Amazon Aurora and Amazon Redshift unlocks opportunities for you to run near real-time analytics and machine learning (ML) on petabytes of transactional data in Amazon Redshift. As this data gets written into Aurora, it will be available in Amazon Redshift within seconds.

It also enables you to run consolidated analytics from multiple Aurora MySQL database clusters in Amazon Redshift to derive holistic insights across many applications or partitions. Amazon Aurora MySQL zero-ETL integration with Amazon Redshift processes over 1 million transactions per minute (an equivalent of 17.5 million insert/update/delete row operations per minute) from multiple Aurora databases and makes them available in Amazon Redshift in less than 15 seconds (p50 latency lag).

Furthermore, you can take advantage of the analytics and built-in ML capabilities of Amazon Redshift, such as materialized views, cross-region data sharing, and federated access to multiple data stores and data lakes.

How Zero-ETL works:

To get started, we need to navigate to Amazon RDS and select Create zero-ETL integration on the Zero-ETL integrations page.

Zero ETL

On the Create zero-ETL integration page, we need to follow a few steps to configure the integration for my Amazon Aurora database cluster and my Amazon Redshift data warehouse.

First, we define an identifier for my integration and select Next.

Zero ETL

On the next page, we need to select the source database by selecting Browse RDS databases.

Zero ETL

Here, we can select my existing database as the source.

Zero ETL

The next step asks us to the target Amazon Redshift data warehouse. Here, we have the flexibility to choose the Amazon Redshift Server-less or RA3 data warehouse in my account or a different account. We select Browse Redshift data warehouses.

Zero ETL

Then, we’ll choose the target data warehouse.

Zero ETL

Because Amazon Aurora needs to replicate into the data warehouse, we need to add an additional resource policy and add the Aurora database as an authorized integration source in the Amazon Redshift data warehouse.

We can solve this by manually updating the Amazon Redshift console or letting Amazon RDS fix it for me. We tick the checkbox.

Zero ETL

On the next page, it shows us the changes that Amazon RDS will perform for us. We’ll select Continue.

Zero ETL

On the next page, we can configure the tags and also the encryption. By default, zero-ETL integration encrypts your data using AWS Key Management Service (AWS KMS), and we have the option to use our own key.

Zero ETL

Then, we need to review all the configurations and select Create zero-ETL integration to create the integration.

Zero ETL

After a few minutes, our zero-ETL integration is successfully created. Then, we switch to Amazon Redshift, and on the Zero-ETL integrations page, we can see that we have our recently created zero-ETL integration.

Zero ETL

Since the integration does not yet have a target database inside Amazon Redshift, we need to create one. 

Zero ETL

Now the integration configuration is complete. On this page, we can see the integration status is active, and there is one table that has been replicated.

Zero ETL

For testing, we create a new table in my Amazon Aurora database and insert a record into this table.

Zero ETL

Then we switched to the Redshift query editor v2 inside Amazon Redshift. Here we can make a connection to the database that we formed as part of the integration. By running a simple query, we can see that our data is already available inside Amazon Redshift.

Zero ETL

The zero-ETL integration is considered very convenient for two reasons.

First, we can unify all data from multiple database clusters together and analyze it in aggregate.

Second, within seconds of the transactional data being written into Amazon Aurora MySQL, this zero-ETL integration seamlessly makes the data available in Amazon Redshift.

Key Benefits of Zero-ETL Integration

The elimination of ETL processes brings forth a myriad of advantages for businesses and data professionals. First and foremost, it significantly reduces the time and resources traditionally spent on data transformations. Real-time data can now flow effortlessly from Amazon Aurora MySQL to Amazon Redshift, enabling faster decision-making and more agile responses to changing business dynamics.

Moreover, zero-ETL integration enhances the overall reliability and consistency of data. By minimizing the number of intermediary steps, the potential for errors or discrepancies is substantially reduced. This ensures that businesses can rely on a more accurate and up-to-date representation of their data, fostering trust in decision-making processes.

A Seamless Journey: How It Works

The zero-ETL integration between Amazon Aurora MySQL and Amazon Redshift is designed for simplicity. By leveraging native integration capabilities, data seamlessly moves between the two services without the need for intricate transformations. This allows users to focus on deriving insights from their data rather than grappling with complex integration processes.

The integration also supports continuous data replication, ensuring that changes in the source database are promptly reflected in the target Redshift cluster. This real-time synchronization empowers businesses to work with the most current information, fostering a more dynamic and responsive data environment.

Embracing the Future of Data Integration

For businesses already leveraging Amazon Aurora MySQL and Amazon Redshift, embracing zero-ETL integration is a straightforward journey. AWS provides comprehensive documentation and resources to guide users through the setup process, making it accessible for both newcomers and seasoned professionals.

In conclusion, the general availability of Amazon Aurora MySQL zero-ETL integration with Amazon Redshift marks a pivotal moment in the evolution of data integration. Businesses can now bid farewell to the complexities of traditional ETL processes, ushering in a new era of efficiency, reliability, and real-time insights. As we collectively step into this future, the promise of streamlined data integration beckons, empowering businesses to thrive in an increasingly data-centric world.
