Sifflet provides real-time metadata observability that detects when different engines, like Spark and Trino, interpret table schemas differently. By tracking atomic commits and metadata snapshots, Sifflet flags compatibility issues early, preventing downstream failures in dashboards or analytics tools.

No, Sifflet does not store your data. We designed our platform to discard any data previews immediately after display, and we only retain metadata like table and column names. This approach supports GDPR compliance and strengthens your overall data governance strategy.

Great question! As AI continues to evolve, the quality and reliability of the data feeding those models becomes even more critical. Data observability ensures that your AI systems are powered by clean, accurate, and up-to-date data. With platforms like Sifflet, organizations can detect issues like data drift, monitor real-time metrics, and maintain data governance, all of which help AI models stay accurate and trustworthy.

Schema monitoring helps catch unexpected changes in your data structure before they break downstream systems like dashboards or ML models. It's a core capability in any modern observability platform because it ensures data reliability and prevents silent failures in your pipelines.

Sentinel is our monitoring agent that automatically recommends the right monitors based on your data’s structure and usage. By analyzing data samples, column patterns, and relationships, it helps teams scale data pipeline monitoring across hundreds of tables without drowning in alerts. It’s a smarter way to ensure data reliability without manual setup.

Using WHERE instead of HAVING when not working with GROUP BY clauses is crucial because WHERE filters data earlier in the query execution. This reduces the amount of data processed, which improves query speed and supports better metrics collection in your observability platform.

Sifflet stands out as a metadata control plane that connects technical reliability with business context. Unlike point solutions, it offers AI-native automation, full data lineage tracking, and cross-functional accessibility, making it ideal for organizations that need to scale trust in their data across teams.

Freshness issues often start with delays in source systems, ingestion bottlenecks, slow transformation jobs, or even caching problems in dashboards. That's why a strong observability platform needs to monitor every stage of the pipeline, from ingestion latency to delivery, to ensure data reliability and timely decision-making.
