TL;DR: Syncing AI agent traces into BigQuery and Iceberg lets teams join decisions, costs, infrastructure, and customer outcomes in SQL, turning observability into a durable data layer for operational and business analysis, according to Arize. The governance implication is that agent telemetry is now a control surface, not just a debugging artifact, and it needs identity-aware retention, access, and audit rules.
Editorial analysis by NHI Mgmt Group, based on content published by Arize: “Data Fabric: Querying agent traces in BigQuery”.
Key questions
Q: What breaks when AI agent traces stay outside the warehouse?
A: Teams lose the ability to join agent decisions with cost, infrastructure, and customer outcomes, so analysis becomes manual and incomplete.
Q: Why do agent traces need stronger governance once they are queryable in SQL?
A: Because trace data can now sit beside billing, infrastructure, and customer records, it inherits the sensitivity of those adjacent datasets.
Q: What are the signs that telemetry agent management is becoming unmanageable?
A: Common warning signs include inconsistent agent configurations, slow rollout of new agents, limited visibility into agent health, and rising data volumes that are not being filtered or deduplicated.
Practitioner guidance
- Define trace data ownership and retention Assign a named owner for agent trace datasets and set retention rules that match their status as durable business records, not temporary logs.
- Apply warehouse access controls to trace tables Restrict who can query trace tables, especially where traces can be joined to billing, CRM, or customer outcome data.
- Separate debugging access from analytical access Give engineers the minimum access needed for investigation and keep broader cross-domain joins for approved analytics roles.
Bottom line: Agent traces become materially more useful when they are stored in a warehouse and joined with billing, infrastructure, and customer data.

Agent traces are becoming business records, not transient telemetry. Once a trace can be joined to billing, customer, and infrastructure data, it acquires the same governance significance as other enterprise records. That changes retention, lineage, and audit requirements because the data now supports operational and financial decisions, not only debugging. Practitioners should govern agent telemetry as a durable dataset with explicit ownership and review processes.
A few things that frame the scale:
- 62% of organisations are at least experimenting with AI agents, but only 23% have scaled one into a single business function, according to McKinsey's 2025 State of AI survey.
A question worth separating out:
Q: How should teams decide who can join agent traces to customer data?
A: Use the same principle you would apply to any sensitive business dataset: grant join access only to roles with a clear analytical need, then log and review those queries. The closer trace data gets to CRM or revenue data, the more important it is to separate operational debugging from business analysis.
