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’s the difference between technical and business data quality?
That's a great distinction to understand! Technical data quality focuses on things like accuracy, completeness, and consistency—basically, whether the data is structurally sound. Business data quality, on the other hand, asks if the data actually supports how your organization defines success. For example, a report might be technically correct but still misleading if it doesn’t reflect your current business model. A strong data governance framework helps align both dimensions.
What makes Monte Carlo a good fit for modern cloud analytics teams?
Monte Carlo shines when you're working with a modern cloud stack and need fast, low-effort data observability. Its ML-driven anomaly detection and metadata-focused monitoring make it easy to catch data issues without writing custom rules. If your team wants to improve dashboard reliability quickly, Monte Carlo is a strong option.
What role does Sifflet’s data catalog play in observability?
Sifflet’s data catalog acts as the central hub for your data ecosystem, enriched with metadata and classification tags. This foundation supports cloud data observability by giving teams full visibility into their assets, enabling better data lineage tracking, telemetry instrumentation, and overall observability platform performance.
What role does data lineage play in incident management and alerting?
Data lineage provides visibility into data dependencies, which helps teams assign, prioritize, and resolve alerts more effectively. In an observability platform like Sifflet, this means faster incident response, better alert correlation, and improved on-call management workflows.
How does the updated lineage graph help with root cause analysis?
By merging dbt model nodes with dataset nodes, our streamlined lineage graph removes clutter and highlights what really matters. This cleaner view enhances root cause analysis by letting you quickly trace issues back to their source with fewer distractions and more context.
What makes debugging data pipelines so time-consuming, and how can observability help?
Debugging complex pipelines without the right tools can feel like finding a needle in a haystack. A data observability platform simplifies root cause analysis by providing detailed telemetry and pipeline health dashboards, so you can quickly identify where things went wrong and fix them faster.
Why is standardization important when scaling dbt, and how does Sifflet support it?
Standardization is key to maintaining control as your dbt project grows. Sifflet supports this by centralizing metadata and enabling compliance monitoring through features like data contracts enforcement and asset tagging. This ensures consistency, improves data governance, and reduces the risk of data drift or unmonitored critical assets.
How does data profiling support GDPR compliance efforts?
Data profiling helps by automatically identifying and tagging personal data across your systems. This is vital for GDPR, where you need to know exactly what PII you have and where it's stored. Combined with data quality monitoring and metadata discovery, profiling makes it easier to manage consent, enforce data contracts, and ensure data security compliance.
