I Tried to Schedule My ETL Pipeline. Here’s What I Didn’t Expect.

An attempt to schedule an ETL pipeline revealed a fundamental portability problem, as the script was initially tied to Google Colab via a hardcoded file path. To solve this, the pipeline was decoupled from Colab by making the database path configurable through an environment variable. The now-portable Python script was then scheduled to run daily using GitHub Actions, configured with a simple YAML workflow file. This process highlighted the crucial difference between simple scheduling and complex orchestration, demonstrating that portability is a prerequisite for automation.
