Frequently asked questions

What can I expect from Sifflet’s upcoming webinar?
Join us on January 22nd for a deep dive into Sifflet’s 2024 highlights and a preview of what’s ahead in 2025. We’ll cover innovations in data observability, including real-time metrics, faster incident resolution, and the upcoming Sifflet AI Agent. It’s the perfect way to kick off the year with fresh insights and inspiration!
What kind of visibility does a data observability platform provide?
A robust data observability platform like Sifflet gives you end-to-end visibility into your data ecosystem. This includes data freshness checks, schema changes, lineage tracking, and anomaly detection. It's like having a complete map of your data journey, helping you proactively manage quality and trust in your analytics.
What are some common data quality issues that can be prevented with the right tools?
Common issues like schema changes, missing values, and data drift can all be caught early with effective data quality monitoring. Tools that offer features like threshold-based alerts, data freshness checks, and pipeline health dashboards make it easier to prevent these problems before they affect downstream systems.
How does Sifflet support data pipeline monitoring at Carrefour?
Sifflet enables comprehensive data pipeline monitoring through features like monitoring-as-code and seamless integration with data lineage tracking and governance tools. This gives Carrefour full visibility into their pipeline health and helps ensure SLA compliance.
What tools can help me monitor data consistency between old and new environments?
You can use data profiling and anomaly detection tools to compare datasets before and after migration. These features are often built into modern data observability platforms and help you validate that nothing critical was lost or changed during the move.
What does Sifflet's recent $12.8M Series A funding mean for the future of data observability?
Great question! This funding round, led by EQT Ventures, allows us to double down on our mission to make data more reliable and trustworthy. With this investment, we're expanding our data observability platform, enhancing real-time monitoring capabilities, and growing our presence in EMEA and the US.
How do declared assets improve data quality monitoring?
Declared assets appear in your Data Catalog just like built-in assets, with full metadata and business context. This improves data quality monitoring by making it easier to track data lineage, perform data freshness checks, and ensure SLA compliance across your entire pipeline.
What non-quantifiable benefits can data observability bring to my organization?
Besides measurable improvements, data observability also boosts trust in data, enhances decision-making, and improves the overall satisfaction of your data team. When your team spends less time debugging and more time driving value, it fosters a healthier data culture and supports long-term business growth.
