View ProjectBuilt for a client focused on collecting structured data from public sources, this ETL-driven solution uses Spring Batch for reliable data processing and Rundeck for orchestration—enabling scalable, automated workflows from extraction to loading. In enterprise-grade data automation, the pairing of Spring Batch and Rundeck is a proven combination for building resilient ETL pipelines. Spring Batch handles the extract-transform-load (ETL) process, offering fault tolerance and chunk-based processing, while Rundeck provides the operational glue—scheduling, triggering, and monitoring batch jobs with precision. In this post, I'll explore how Spring Batch powers the core ETL logic and how Rundeck integrates seamlessly to schedule and manage these jobs at scale.
