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 metadata play in a data observability platform?
Metadata provides context about your data, such as who created it, when it was modified, and how it's classified. In a data observability platform, strong metadata management enhances data discovery, supports compliance monitoring, and ensures consistent, high-quality data across systems.
What is dbt Impact Analysis and how does it help with data observability?
dbt Impact Analysis is a new feature from Sifflet that automatically comments on GitHub or GitLab pull requests with a list of impacted assets when a dbt model is changed. This helps teams enhance their data observability by understanding downstream effects before changes go live.
Why is technology critical to scaling data governance across teams?
Technology automates key governance tasks such as data classification, access control, and telemetry instrumentation. With the right tools, like a data observability platform, organizations can enforce policies at scale, detect anomalies automatically, and integrate governance into daily workflows. This reduces manual effort and ensures governance grows with the business.
What is data observability and why is it important?
Data observability is the ability to monitor, understand, and troubleshoot data systems using real-time metrics and contextual insights. It's important because it helps teams detect and resolve issues quickly, ensuring data reliability and reducing the risk of bad data impacting business decisions.
What kind of metadata can I see for a Fivetran connector in Sifflet?
When you click on a Fivetran connector node in the lineage, you’ll see key metadata like source and destination, sync frequency, current status, and the timestamp of the latest sync. This complements Sifflet’s existing metadata like owner and last refresh for complete context.
Why is data observability becoming essential for modern data teams?
As data pipelines grow more complex, data observability provides the visibility needed to monitor and troubleshoot issues across the full stack. By adopting a robust observability platform, teams can detect anomalies, ensure SLA compliance, and maintain data reliability without relying on manual checks or reactive fixes.
How do I ensure SLA compliance during a cloud migration?
Ensuring SLA compliance means keeping a close eye on metrics like throughput, resource utilization, and error rates. A robust observability platform can help you track these metrics in real time, so you stay within your service level objectives and keep stakeholders confident.
How can I keep passive metadata accurate and useful over time?
To maintain high-quality passive metadata, Sifflet recommends a mix of automated ingestion and manual curation. Connect your data sources, standardize tagging, build a business glossary, and schedule regular reviews. This helps ensure your data profiling and data validation rules stay aligned with evolving business needs.
