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
How does Sifflet help with end-to-end data observability?
Sifflet enhances end-to-end data observability by allowing you to declare any asset in your data stack, including custom applications and scripts. This ensures full visibility into your data pipelines and supports comprehensive data lineage tracking and root cause analysis.
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.
What are the five technical pillars of data observability?
The five technical pillars are freshness, volume, schema, distribution, and lineage. These cover everything from whether your data is arriving on time to whether it still follows expected patterns. A strong observability tool like Sifflet monitors all five, providing real-time metrics and context so you can quickly detect and resolve issues before they cause downstream chaos.
How does Sifflet help with data observability during the CI process?
Sifflet integrates directly with your CI pipelines on platforms like GitHub and GitLab to proactively surface issues before code is merged. By analyzing the impact of dbt model changes and running data quality monitors in testing environments, Sifflet ensures data reliability and minimizes production disruptions.
How does Sifflet support root cause analysis when a deviation is detected?
Sifflet combines distribution deviation monitoring with field-level data lineage tracking. This means when an anomaly is detected, you can quickly trace it back to the source and resolve it efficiently. It’s a huge time-saver for teams managing complex data pipeline monitoring.
Why are containers such a big deal in modern data infrastructure?
Containers have become essential in modern data infrastructure because they offer portability, faster deployments, and easier scalability. They simplify the way we manage distributed systems and are a key component in cloud data observability by enabling consistent environments across development, testing, and production.
What role does anomaly detection play in modern data contracts?
Anomaly detection helps identify unexpected changes in data that might signal contract violations or semantic drift. By integrating predictive analytics monitoring and dynamic thresholding into your observability platform, you can catch issues before they break dashboards or compromise AI models. It’s a core feature of a resilient, intelligent metadata layer.
What can I expect from Sifflet at Big Data Paris 2024?
We're so excited to welcome you at Booth #D15 on October 15 and 16! You’ll get to experience live demos of our latest data observability features, hear real client stories like Saint-Gobain’s, and explore how Sifflet helps improve data reliability and streamline data pipeline monitoring.
