A logistics company deploys an AI agent to monitor inventory and automatically trigger reorders. The model is solid. The prompts are well-engineered. The agent connects to their analytics environment and starts running.
Three weeks in, it fires a reorder for a product that had already been restocked because the data it was querying was a 24-hour-old extract sitting in a secondary platform. The warehouse had the inventory, but the agent didn’t know. That’s an architecture problem.
Most enterprises are discovering this the hard way. They’ve invested heavily in foundation models, built out prompting workflows, and connected agents to their data, only to find those agents returning conflicting numbers depending on which system they happened to query.
The numbers reflect it. MIT’s Project NANDA found that roughly 95% of AI pilots show no measurable P&L impact. Gartner forecasts that more than 40% of agentic AI projects will be abandoned by next year due to unclear outcomes and poor integration.
Fragmented data pipelines and inconsistent definitions are primary reasons AI initiatives fail to scale, and both are direct consequences of how enterprises are moving data.
AI Agents Fail Without Trusted Data
Think about the difference between a traffic report and a self-driving car. Checking a traffic report before you drive is conversational BI: you get information, apply judgment, and decide. A self-driving car is agentic analytics. It doesn’t ask for directions. It navigates in real time and acts on what it sees.
A self-driving car only works because it runs on live sensors. If you gave it yesterday’s traffic data, it would fail immediately. It wouldn’t see the accident three miles ahead. It would act on information with confidence that no longer reflects reality.
When AI agents run on extracted data, they operate on snapshots rather than signals.
The pattern I see most often is enterprises with data on Snowflake extracting that data into a secondary platform, such as Microsoft Fabric, a local data store, or a pipeline feeding an AI agent, to enable “AI-ready” analytics. It seems reasonable on the surface. In practice, it introduces exactly the kind of architectural debt that makes autonomous AI impossible.
Why Data Extraction Is Not the Answer
When you extract data out of your cloud data platform into a secondary environment, you’re no longer running AI on live data. You’re running it on a snapshot of what was true at the time of the last pipeline run.
A human analyst reviewing a dashboard can tolerate a few hours of latency. They apply judgment, cross-reference, and flag anomalies. An autonomous agent cannot. It takes the data at face value and acts on it.
This creates three compounding problems.
Delayed signals. A supply chain agent monitoring inventory levels or a financial agent tracking cash positions needs to act on the current state. Snapshot-based architectures ensure the agent is always operating on past states.
Conflicting metric definitions. When data exists in multiple places, such as copies in Snowflake, Fabric, or a vector store, those copies inevitably diverge. Each system may apply different transformation logic, different business rules, and different aggregations. The result is agents that return different values for the same question depending on which data source they happen to hit. Our own testing shows that LLMs querying databases directly, without a semantic layer, are wrong roughly 80% of the time when a query requires joining more than 4 or 5 tables. That’s an unacceptable failure rate for systems designed to take autonomous action.
Governance fragmentation. The moment you extract data from a governed platform, you inherit a second governance perimeter, access controls, row-level security, and audit trails. Maintaining consistency across multiple environments is substantial. Most organizations don’t keep up with it, which means the AI operates outside the governance boundaries the enterprise actually cares about.
The difference between extract-based analytics and live connectivity ultimately comes down to whether AI systems operate on snapshots or signals.
| Snapshot Architecture (Extract-Based) | Signal Architecture (Live Semantic Model) |
| Data copied across platforms | Queries run directly on the source data platform |
| Batch pipelines introduce latency | AI agents access live business signals |
| Metrics redefined across tools | Metrics are defined once in a governed semantic layer |
| Governance is applied inconsistently across environments | Governance is unified, applied on data at rest, and enforced centrally |
| AI agents operate on historical snapshots | BI tools and AI agents share the same definitions |
Agentic analytics requires live data architectures, not snapshot architectures.
Live Connectivity as an AI Requirement
Agentic analytics requires the same data discipline that good BI has always required, but with zero tolerance for inconsistency. The architecture requires three things.
Live semantic models. The agent needs access to the data as it actually exists right now, not a periodic copy. A self-driving car’s sensors don’t pull from a database of yesterday’s road conditions. They read the environment in real time. Live connectivity to your cloud data platform gives agents the same capability. Queries hit the source directly with no intermediate layer introducing latency or state divergence.
Shared semantic definitions across AI and BI. The metric a CFO sees on a dashboard and the metric an agent uses to trigger a procurement workflow must be the same, defined once and enforced consistently. A universal semantic layer becomes the control plane for analytics and AI, standardizing metric definitions, enforcing governance policies, and ensuring every system operates from the same business logic. Independent benchmarks show that LLMs paired with semantic layers achieve accuracy rates of 100%, compared to roughly 20% when querying databases directly. That gap is the difference between a system that’s unreliable in production and one that’s trustworthy. When definitions exist only in BI tools, agents operating outside those tools are working with raw SQL or a loosely interpreted schema. Neither is trustworthy at scale.
Centralized access controls. Row-level security, column masking, and role-based access policies should be enforced at the semantic layer rather than re-implemented for each consumption point. When an agent queries data through the semantic layer, it operates within the same governance boundaries as every other user. There’s no separate permission set to maintain, and no risk of the agent seeing data it shouldn’t.
At AtScale, the Model Context Protocol (MCP) server is how we expose this governed semantic model to AI agents. MCP gives agents a machine-readable interface to discover metrics, dimensions, relationships, and business context in real time. The agent is operating with semantic understanding, not just table access.
The Cost Dimension of Data Extraction
Beyond governance and accuracy, there’s a straightforward cost argument for live connectivity over extraction.
The extraction approach compounds this further. ETL processes land data in Snowflake, and organizations pay egress costs to copy it to secondary platforms. That creates double compute charges: once in the originating platform and again in the destination, plus pipeline duplication and the ancillary infrastructure required to keep them synchronized. Organizations that have moved from an extract-based approach to live connectivity with AtScale on Snowflake have seen 30–70% TCO reductions. The savings come from eliminating redundant pipelines, removing data movement overhead, and consolidating compute onto a single governed platform.
Avoiding compute explosion is often what determines whether agentic analytics is operationally sustainable at enterprise scale.
The Standard for Autonomous AI
The architecture required to make AI actually work in production isn’t new technology. It’s the application of disciplines that the data industry has understood for decades. Governance, consistency, a single source of truth. Each of these needs to be rigorously applied to the agentic workloads now being deployed. The organizations that get this right will be the ones that can trust their agents.
