A logistics technology provider required a reliable and automated ETL framework to process shipping and transactional data for its e-commerce partners. By leveraging AWS Glue jobs integrated with Amazon Aurora PostgreSQL, the company has modernised its data integration pipelines, reduced operational overhead, and accelerated delivery of analytics-ready data.

The Challenge

The company faced significant challenges with its legacy ETL approach:

• Manual scripts created inconsistencies in data quality.
• ETL pipelines lacked automation and monitoring, leading to delays.
• Scaling was difficult as shipping volumes fluctuated heavily.
• Analysts had limited access to trusted data in near real-time.
• High maintenance costs for infrastructure running data pipelines.

Our Solution

AWS Glue was selected to modernise the ETL framework.

• AWS Glue Jobs: Transformed raw shipping and partner data stored in Amazon S3 and ingested into Aurora.
• Glue Crawlers: Automated schema discovery and maintained metadata in the AWS Glue Data Catalog.
• Aurora PostgreSQL Integration: Used Glue’s JDBC connectors to load transformed datasets directly into Aurora tables.
• Job Orchestration & Monitoring: AWS Glue Studio provided job workflows while Amazon CloudWatch enabled performance monitoring and alerts.
• Scalable Serverless Processing: Glue automatically scaled with workload spikes during peak shipping seasons.

The Result

Automation: Replaced manual ETL scripts with automated Glue jobs, reducing manual intervention by 75%.

• Faster Data Availability: Reduced ETL cycle time from 4 hours to under 30 minutes.
• Improved Data Quality: Standardised validation and enrichment rules applied in Glue led to a 90% reduction in data inconsistencies.
• Scalability: Seamlessly handled seasonal order spikes without additional infrastructure.
• Business Enablement: Analysts gained near real-time access to high-quality operational data for logistics optimisation.
