Build an ETL service pipeline to load data incrementally from Amazon S3 to Amazon Redshift using AWS Glue

The Incremental ETL Pipeline with AWS Glue template shows how to create an incremental ETL pipeline with AWS Glue, Amazon S3, and Amazon Redshift. ETL is an acronym for Extract, Transform, and Load. It is an operation of pulling data from a source, cleaning or transforming it, and inserting it into a destination where it will be used. In such a scenario, the data is retained in Amazon S3. You process and transform it using AWS Glue. You then load the data into Amazon Redshift, a data warehouse used for analytics and reports.
 

The best thing about the template is that it does not reload everything each time. It reloads only the changed or the new ones. This is what they call an incremental load. It is time, money, and resource efficient.

Why this template is a game changer ?

Typically, when replicating data from storage into a data warehouse, most organizations reload the whole dataset every time. Even if barely, anything has changed, the system replicates all the work.

This template changes that. It is built to process only what is needed:

• It is searching for new or current information.

• It saves you from doing repetitive processing every day.

• It is serverless, built on top of AWS Glue, so you don't provision infrastructure or servers.

• It scales seamlessly as your data grows.

• It is following security best practices, so your data is secure.

In simple terms, this template speeds up your data pipeline, makes it cheaper, and easier to maintain.

Who can use this template, and when? 

This is a blueprint for anyone working with data and would like to ensure that their warehouse is always current without wasting time or money.

It is beneficial if you are: 

• A data engineer building routine data loads.

• A data analyst who needs fresh data in Redshift for reporting purposes.

• A business team that relies on reliable dashboards.

• A small group which desires to implement automation with less coding.

It is best to use the Incremental ETL Pipeline with AWS Glue template when your S3 data keeps changing, like hour by hour or day by day, and you would like Redshift to synchronize without reloading it all. It is also great when you wish to have a setup that is less maintenance and runs in a secure environment.

What are the main components of the template? 

These are the components of this pipeline and what they accomplish in plain language:

• Amazon S3 – This is where your raw data and processed data live. Think of it as a cloud storage folder.

• AWS Glue – This is the brain of the process. It cleans, transforms, and prepares the data before loading it into Redshift.

• Amazon Redshift – This is where your warehouse resides. It maintains the data in a form that is analytic and report ready.

• AWS Lambda – This is a helper that starts the process when new data arrives or on a schedule.

• NAT Gateway – It secures your connection with AWS services and keeps it protected.

• Data Processing Engine – This is the AWS Glue engine that actually processes and cleans the data.

• Amazon CloudWatch – It monitors your pipeline and notifies you if anything is wrong.

• IAM Roles – These ensure that the appropriate people and services are authorized to access your data.

• S3 Buckets – These isolate raw data from processed data, so everything is in its place.

• Workflow Scheduler – This determines when your ETL jobs execute, such as every night or every hour.

• Data Lake – Here, semi‑structured and structured data are stored in S3.

• Logging & Monitoring – These records what is occurring and helps the troubleshooting process if necessary.

All these components co-operate so that your pipeline flows smoothly and safely.

 How to begin with Cloudairy ?

It is simple and quick to install this template in Cloudairy. Here's how:

• Login to your Cloudairy account.

• Go to the Templates page within the dashboard.

• Find ETL Pipeline with AWS Glue in the template library.

• Click on the template to view a preview.

• Click Open to begin working on it.

• Set up the AWS Glue jobs and specify the transformations you require.

• Link your S3 buckets to your Redshift cluster.

• Make the workflow fit into your own timing or triggers.

• Save your setup or export it for deployment.

After you do that, your pipeline is ready to execute. You can also collaborate with other Cloudairy coworkers to modify or extend the workflow.

Summary 

This is a straightforward approach to creating an incremental ETL pipeline with AWS Glue. It reads the data from Amazon S3, transforms it, and writes it to Amazon Redshift without loading the entire thing every time. With serverless processing through AWS Glue, orchestration through Lambda, and monitoring through CloudWatch, this pipeline is simple to monitor and secure.


The Incremental ETL Pipeline with AWS Glue template is cost-effective and time-effective, and it maintains your data in an analytics-ready state. You can readily open and install this workflow in Cloudairy in a matter of steps, and it is a cost-effective measure for teams who don't want to put in extra effort to handle growing data. If you require an S3 to Redshift ETL pipeline, desire AWS Glue for incremental data loading, or are investigating serverless data integration and even AWS Glue alternatives, this template is a good place to start.
