What exactly is data quality, and why should teams care about it?
Data quality refers to how accurate, complete, consistent, and timely your data is. It's essential because poor data quality can lead to unreliable analytics, missed business opportunities, and even financial losses. Investing in data quality monitoring helps teams regain trust in their data and make confident, data-driven decisions.
How do I ensure SLA compliance during a cloud migration?

How does Sifflet support SLA compliance and proactive monitoring?
With real-time metrics and intelligent alerting, Sifflet helps ensure SLA compliance by detecting issues early and offering root cause analysis. Its proactive monitoring features, like dynamic thresholding and auto-remediation suggestions, keep your data pipelines healthy and responsive.
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’s next for data observability at Sifflet?
We’re focused on solving the next generation of challenges, like hybrid environments, end-to-end data lineage tracking, and scaling data trust. Whether it's batch data observability or real-time pipeline monitoring, our mission is to help organizations build resilient, transparent, and future-proof data stacks.

Absolutely! By surfacing connector statuses and metadata directly in the lineage graph and catalog, Sifflet helps you stay on top of pipeline health and detect issues early. It's a powerful step forward in proactive data pipeline monitoring.
How can Sifflet help ensure SLA compliance and prevent bad data from affecting business decisions?
Sifflet helps teams stay on top of SLA compliance with proactive data freshness checks, anomaly detection, and incident tracking. Business users can rely on health indicators and lineage views to verify data quality before making decisions, reducing the risk of costly errors due to unreliable data.
