A schema is the structure that defines the contents of the data warehouse. It's the logical description of your entire database, and changes can lead to major issues in your data environment. Unfortunately, schema drift is a common issue that often occurs unexpectedly. Fixing a warehouse schema change can be a frustrating and time-intensive process, not to mention the possible nightmare changes can create downstream. Optimize your data structure!

Fortunately, modern data problems paved the way for highly efficient solutions. The right data monitoring platform can provide schema change alerts, ensuring you stay one step ahead of the drift. Here's why you need a platform to detect schema changes.

Quick Intervention

The biggest reason you should invest in monitoring platforms is to ensure you can take action whenever necessary. The problem with schema drift is that it happens subtly. For example, your upstream sources could make new additions, delete entities or make type changes to columns and tables. Someone can also inadvertently rename entities or make alterations with wide-reaching effects.

Those changes can be subtle. No one's monitoring the warehouse schema 24/7. As a result, they often go unnoticed until those changes present bigger downstream problems across your entire data stack.

Monitoring tools provide real-time alerts whenever a warehouse schema change occurs. Learn about the changes that happen and take action if necessary. The earlier you catch those problems, the lighter their impact will be.

Debug Older Problems

What happens if you don't take action and the schema change causes issues much later? A monitoring platform can still help you in that situation. These platforms go beyond real-time monitoring. They can also provide historical data that comes in handy when debugging.

View the entire history of changes that occurred to the warehouse schema. See where things went wrong and know precisely what you need to address.

Upstream Monitoring

Another huge perk of monitoring platforms is that you can use them to keep an eye on upstream application databases. By setting sights on the upstream databases, you can get alerts and stay ahead of changes before they even hit your warehouse!
