The embarrassing truth about stale data

Product

Imagine.

You’re a technical lead or a data analyst at a global bank.

Your bank relies on real-time data feeds — such as interest rates, housing data, stock data, and sensitive customer information — to make critical financial decisions and adjust loan prices. 

If the Federal Reserve raises rates overnight, and your systems fail to check the freshness of the interest rate data feed, you may end up providing loans at incorrect rates.

Moreover, if a technical glitch occurs, causing feeds to stop loading or carry partial loads, you’ll see missing, partial, or incorrect data used by downstream applications. Your bank might end up making inaccurate stock trading decisions or sending out incorrect customer communications.

Even worse, data downtime events like these can irreparably damage reputation — yours and the bank. 

Customers, investors, and regulators might lose trust in your organization’s ability to effectively manage risk and maintain the integrity of your data, potentially leading to a decline in business and more stringent regulatory oversight.

What’s the root cause of so much potential damage? Stale data.

The truth is stale data is not only bad for business, it’s embarrassing. Not only to the organization, but to the data professionals responsible for ensuring the data is up to date.

Luckily, you can stop stale data and ensure you and your organization avoid damage to your reputation. To do so, we need to use data observability to monitor the freshness of our pipelines and alert to stale data.

Do you want to be notified in Slack or from the CEO?

No one wants to get bad news from the boss, especially dataOps and Engineering teams. 

You want early warning notifications via email, Slack or Teams so you can resolve issues before the effects of stale data move downstream and create inaccurate BI reports, undermine the customer experience, and worse. 

To achieve early warning detection, you need something in place that can constantly monitor what normal looks like across all data feeds and alert you when things look abnormal. 

This type of monitoring is commonly referred to as data observability (and we offer Collibra Data Quality & Observability). 

Data observability is exploding in popularity across enterprises globally because of the dramatic business impact a Stale Data event can have — and, above all, the costly damages that can be avoided if issues are identified and resolved within a  few hours, instead of a few days.

Monitor 1,000s of pipelines

A data outage can be quite obvious on a single data feed level. 

However, the problem becomes more complex when trying to manage hundreds of data feeds across different users, permissions, and business units. As is often the case, the feeds flow from a downstream system to a cloud database, only increasing the complexity and potential damage. 

Collibra Data Quality and Observability simplifies seeing the big picture as well providing a drill down into more detailed, single data pipeline views.

Collibra helps you see inside data pipelines to reveal blind spots in your data operations.

Write a Stale Data check

Sometimes, a data engineer or analyst may want to manually write a Stale Data check. 

For convenience, the Collibra Data Quality & Observability offers a SQL editor with shortcut variables called “stat rules,” which gives you full control at the dataset level and the ability to define unique conditional cases.
