Pinpoint where the issue is occurring—whether in data loading, transformation, or integration. Use logging tools to identify errors in real-time and set alerts for any anomalies to catch problems immediately. Work closely with your team to review recent changes and ensure everyone follows best practices. If possible, run updates in a test environment before going live to prevent delays. By staying organized and addressing issues as they arise, you can quickly resolve problems and keep updates on track.
-
Replicate the same update setup into the staging or development environment and try to do all kinds of validations/testing according to the requirement and do quality checks and if everything is going fine after the update and then push the changes into the production and in production implement alert systems and notifications and if it is not delivering the expected results or failure if failures are routine try to do automations or if any Database issue implement the horizontal scaling methodology that will help latency
-
Identify root causes of any issues. Have a centralized and standardized methodology for approaching etl and data engineering management tasks. Standardization is key, as well as using tools such as dbt to manage workflows within the data warehouse.
