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
What role does data observability play in modern data architecture?
Data observability helps ensure your architecture remains reliable and trustworthy as it evolves. It provides real-time visibility into data quality, freshness, and structure across pipelines, making it easier to catch issues early and maintain consistency across systems.
How does Sifflet help with real-time anomaly detection?
Sifflet uses ML-based monitors and an AI-driven assistant to detect anomalies in real time. Whether it's data drift detection, schema changes, or unexpected drops in metrics, our platform ensures you catch issues early and resolve them fast with built-in root cause analysis and incident reporting.
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 use AI to improve data observability?
At Sifflet, we're integrating advanced AI models into our observability platform to enhance data quality monitoring and anomaly detection. Marie, our Machine Learning Engineer, has been instrumental in building intelligent systems that automatically detect issues across data pipelines, making it easier to maintain data reliability in real time.
Does Sifflet store any of my company’s data?
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.
How does the new Fivetran integration enhance data observability in Sifflet?
Great question! With our new Fivetran integration, Sifflet now provides visibility into your data's journey even before it reaches your data platform. This means you can track data from its source through Fivetran connectors all the way downstream, offering truly end-to-end data observability.
What’s new in Sifflet’s data quality monitoring capabilities?
We’ve rolled out several powerful updates to help you monitor data quality more effectively. One highlight is our new referential integrity monitor, which ensures logical consistency between tables, like verifying that every order has a valid customer ID. We’ve also enhanced our Data Quality as Code framework, making it easier to scale monitor creation with templates and for-loops.
How does data lineage tracking help with root cause analysis in data integration?
Data lineage tracking gives visibility into how data flows from source to destination, making it easier to pinpoint where issues originate. This is essential for root cause analysis, especially when dealing with complex integrations across multiple systems. At Sifflet, we see data lineage as a cornerstone of any observability platform.
