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 use AI to improve data classification?
Sifflet leverages machine learning to provide AI Suggestions for classification tags, helping teams automatically identify and label key data characteristics like PII or low cardinality. This not only streamlines data management but also enhances data quality monitoring by reducing manual effort and human error.
What’s the difference between static and dynamic freshness monitoring modes?
Great question! In static mode, Sifflet checks whether data has arrived during a specific time slot and alerts you if it hasn’t. In dynamic mode, our system learns your data arrival patterns over time and only sends alerts when something truly unexpected happens. This helps reduce alert fatigue while maintaining high standards for data quality monitoring.
How does Sifflet reduce alert fatigue compared to other observability tools?
Sifflet reduces alert fatigue by using AI agents to prioritize alerts based on business impact and historical patterns. It avoids bombarding teams with irrelevant notifications by tuning its anomaly detection models to focus on what truly matters. This makes your observability dashboards more actionable and less overwhelming.
What is agentic observability and how is it different from traditional observability tools?
Agentic observability goes beyond just surfacing logs and metrics. It uses AI agents to understand what broke, why it broke, what it impacts, and even suggests or takes action to fix it. Unlike traditional observability tools that rely on human interpretation, an observability platform like Sifflet automates root cause analysis and incident response, making data pipeline monitoring far more efficient.
How do organizations monitor the success of their data governance programs?
Successful data governance is measured through KPIs that tie directly to business outcomes. This includes metrics like how quickly teams can find data, how often data quality issues are caught before reaching production, and how well teams follow access protocols. Observability tools help track these indicators by providing real-time metrics and alerting on governance-related issues.
What are some engineering challenges around the 'right to be forgotten' under GDPR?
The 'right to be forgotten' introduces several technical hurdles. For example, deleting user data across multiple systems, backups, and caches can be tricky. That's where data lineage tracking and pipeline orchestration visibility come in handy. They help you understand dependencies and ensure deletions are complete and safe without breaking downstream processes.
What kind of visibility does Sifflet provide for Airflow DAGs?
Sifflet offers a clear view of DAG run statuses and their potential impact on the rest of your data pipeline. Combined with data lineage tracking, it gives you full transparency, making root cause analysis and incident response much easier.
Why is data observability becoming so important for businesses in 2025?
Great question! As Salma Bakouk shared in our recent webinar, data observability is critical because it builds trust and reliability across your data ecosystem. With poor data quality costing companies an average of $13 million annually, having a strong observability platform helps teams proactively detect issues, ensure data freshness, and align analytics efforts with business goals.
