Google BigQuery
Integrate Sifflet with BigQuery to monitor all table types, access field-level lineage, enrich metadata, and gain actionable insights for an optimized data observability strategy.




Metadata-based monitors and optimized queries
Sifflet leverages BigQuery's metadata APIs and relies on optimized queries, ensuring minimal costs and efficient monitor runs.


Usage and BigQuery metadata
Get detailed statistics about the usage of your BigQuery assets, in addition to various metadata (like tags, descriptions, and table sizes) retrieved directly from BigQuery.
Field-level lineage
Have a complete understanding of how data flows through your platform via field-level end-to-end lineage for BigQuery.


External table support
Sifflet can monitor external BigQuery tables to ensure the quality of data in other systems like Google Cloud BigTable and Google Cloud Storage

Frequently asked questions
When should organizations start thinking about data quality and observability?
The earlier, the better. Building good habits like CI/CD, code reviews, and clear documentation from the start helps prevent data issues down the line. Implementing telemetry instrumentation and automated data validation rules early on can significantly improve data pipeline monitoring and support long-term SLA compliance.
What happens when there's a data incident in Sifflet?
When a data incident occurs, Sifflet’s Sage and Forge tools kick in. Sage consolidates all alerts into a clear incident narrative, while Forge recommends fixes based on past resolutions. This streamlines incident management workflows and helps teams restore data trust quickly and efficiently.
How does Sifflet support real-time data lineage and observability?
Sifflet provides automated, field-level data lineage integrated with real-time alerts and anomaly detection. It maps how data flows across your stack, enabling quick root cause analysis and impact assessments. With features like data drift detection, schema change tracking, and pipeline error alerting, Sifflet helps teams stay ahead of issues and maintain data reliability.
How does data observability help detect data volume issues?
Data observability provides visibility into your pipelines by tracking key metrics like row counts, duplicates, and ingestion patterns. It acts as an early warning system, helping teams catch volume anomalies before they affect dashboards or ML models. By using a robust observability platform, you can ensure that your data is consistently complete and trustworthy.
Who should be responsible for managing data quality in an organization?
Data quality management works best when it's a shared responsibility. Data stewards often lead the charge by bridging business needs with technical implementation. Governance teams define standards and policies, engineering teams build the monitoring infrastructure, and business users provide critical domain expertise. This cross-functional collaboration ensures that quality issues are caught early and resolved in ways that truly support business outcomes.
What is data distribution deviation and why should I care about it?
Data distribution deviation happens when the distribution of your data changes over time, either gradually or suddenly. This can lead to serious issues like data drift, broken queries, and misleading business metrics. With Sifflet's data observability platform, you can automatically monitor for these deviations and catch problems before they impact your decisions.
How has AI changed the way companies think about data quality monitoring?
AI has definitely raised the stakes. As Salma shared on the Joe Reis Show, executives are being asked to 'do AI,' but many still struggle with broken pipelines. That’s why data quality monitoring and robust data observability are now seen as prerequisites for scaling AI initiatives effectively.
Is there a networking opportunity with the Sifflet team at Big Data Paris?
Yes, we’re hosting an exclusive after-party at our booth on October 15! Come join us for great conversations, a champagne toast, and a chance to connect with data leaders who care about data governance, pipeline health, and building resilient systems.
