The six-layer architecture that makes agentic data pipelines reason, act, and learn.
Each of the six layers has a distinct role. Together, they form a system that can observe its own state, understand what went wrong, fix it, and remember what it learned for next time.
Six layers, each with a distinct responsibility. No single layer makes a pipeline agentic; it is the interaction between them that does.
The pipeline's purpose is explicitly encoded: the business outcome it supports, the consumers it serves, and the quality and freshness standards it must meet. Intent is what allows every other layer to make decisions; without it, agents have no reference point for what "correct" looks like.
A team of specialist AI agents operates across every stage of the pipeline lifecycle: ingestion, transformation, data quality, and repair. An orchestrating agent coordinates them; deciding when to intervene, which agent to deploy, and how to respond to changing conditions. Agents reason and act rather than follow static instructions.
The compute and orchestration layer where pipeline jobs are triggered, scheduled, and run. Execution is dynamic; agents can modify, pause, or reroute workflows in real time when conditions change. Existing tools like Airflow, dbt, and Spark operate at this layer.
The sources, warehouses, lakes, vector stores, and streaming systems the pipeline reads from and writes to. Agentic data pipelines serve both traditional analytical consumers and AI-native consumers; the data systems layer must deliver data in formats appropriate for each.
Continuous monitoring of pipeline health, data quality, schema integrity, and performance signals. Observability is what enables the autonomous data loop; without it, agents are blind. Every signal the observability layer captures feeds the agent layer's ability to reason about pipeline state.
Every incident, repair, and decision is retained as operational knowledge. Memory allows the pipeline to learn from past failures, improve diagnostic accuracy over time, and reduce the frequency of human intervention. Memory is what distinguishes a self-healing pipeline from one that merely restarts on failure.
The six layers don't operate independently; they form a continuous feedback loop.
The Intent layer defines what success looks like. The Observability layer monitors whether success is being achieved. When it detects a deviation, the Agent layer diagnoses the cause and determines a response. The Execution layer carries out that response. The Memory layer records what happened and what worked.
Over time, the pipeline gets better at recognizing and resolving the same class of problems; faster to diagnose, more accurate to repair, and less likely to need human intervention. This is the Autonomous Data Loop in architectural form: Observe → Diagnose → Repair → Learn.
The Intent layer gives agents the context they need to make decisions. It is the reference point every other layer reasons against.
Observability, Agents, and Memory work in concert; Observability surfaces the problem, Agents resolve it, Memory retains what was learned.
The Agent layer is the coordination layer; an orchestrating agent directs specialist agents across ingestion, transformation, data quality, and repair.
