Scenario: You are responsible for managing ETL testing processes for a data warehouse. How can you ensure that the ETL jobs are executed at the right time and in the correct sequence?
- Execute ETL jobs based on developer availability
- Implement job scheduling and orchestration tools
- Set up cron jobs on individual servers
- Use manual scheduling with Excel spreadsheets
To ensure ETL jobs are executed at the right time and in the correct sequence for a data warehouse, it's advisable to implement job scheduling and orchestration tools. These tools provide features for defining dependencies between jobs, scheduling tasks at specific times, and managing job execution workflows. By leveraging such tools, testers can streamline ETL testing processes, improve efficiency, and maintain the integrity of data pipelines.
