Problem

Domain: Database operations debugging

Databricks engineers had to debug thousands of OLTP databases across clouds using fragmented dashboards, CLI commands, logs, and expert knowledge.

Constraints:

Architecture

Databricks turned fragmented MySQL incident investigation into a centralized agentic debugging platform. A chat assistant sits over metrics, dashboards, CLI/log data, and operational workflows, but the important system-design move is the foundation underneath it: a central-first sharded Storex architecture, fine-grained access control, and unified orchestration across clouds, regions, and regulatory domains. The assistant can retrieve metrics/logs, correlate signals, answer follow-ups, and guide engineers without requiring storage-team experts for every investigation.

Data flow

An engineer asks the chat assistant about service health or a database incident. The platform retrieves metrics and logs, correlates them through the centralized debugging layer, applies region/cloud/access abstractions, and returns an interactive diagnostic path. Feedback from engineers shifted the system from a static SOP checklist to anomaly surfacing and then to a chat assistant that codified debugging knowledge and produced next-step guidance.

“During a typical MySQL incident investigation, an engineer would often * Check metrics in Grafana * Switch to a Databricks dashboard to understand the client workload”article, stated
“The real breakthrough came with a chat assistant that codifies debugging knowledge, answers follow-ups, and turns investigations into an interactive process.”article, stated
“Any agent would need to handle region- and cloud-specific logic. And without centralized access controls, it would become either too restrictive to be useful or too permissive to be safe.”article, implied

Why this architecture

Individual debugging tools already existed, but the workflow cost engineers SLO budget because context lived across tabs, dashboards, CLIs, and cloud consoles. Databricks therefore built abstraction, centralization, access control, and orchestration first, then layered the chat assistant on top so the agent had a consistent operational landscape to reason over safely.

Scale

Alternatives considered (roads not taken)

Keep separate Grafana, dashboard, CLI, and cloud-console workflows

Rejected because: Those tools worked individually but did not form a cohesive incident workflow.

“Each tool worked fine on its own, but together they failed to form a cohesive workflow or provide end-to-end insight.”article, stated

Static agentic workflow following a debugging SOP

Rejected because: Engineers wanted immediate diagnostic insight rather than a manual checklist.

“Our v1 was a static agentic workflow that followed a debugging SOP, but it wasn’t effective — engineers wanted a diagnostic report with immediate insights, not a manual checklist.”article, stated

Anomaly detection alone

Rejected because: It surfaced anomalies but did not provide clear next steps.

“This strategy led to anomaly detection, which surfaced the right anomalies, but still didn’t provide clear next steps.”article, stated

Patterns

observability-tracing (operations)

The agent retrieves metrics/logs and correlates signals across the database fleet.

“Our AI agent interprets, executes, and debugs by retrieving key metrics and logs, and automatically correlating signals.”article, stated

tool-use-orchestration (operations)

The platform unifies dashboards, CLI-style database inspection, cloud logs, and operational workflows behind an intelligent interface.

“* Fragmented tooling Engineers juggled dashboards, CLIs, and manual steps for investigation and operations like restarts or restores.”article, implied

Tradeoffs

How to start an AI debugging platform.

Chose small hackathon prototype plus on-call shadowing over large up-front multi-quarter build.

Rationale: A fast prototype exposed value, then user research grounded the production direction.

“Instead, we tested the idea during a company-wide hackathon.”article, stated

Gotchas (what bit them)

All individual debugging tools worked, but the workflow did not.

Root cause: Incident response required stitching together hypotheses across disconnected systems, burning SLO time.

Resolution: Build a unified data/workflow foundation before layering intelligence on top.

“Each tool worked fine on its own, but together they failed to form a cohesive workflow or provide end-to-end insight.”article, stated

Evaluation

Databricks reports debugging-time reduction, adoption, and new-engineer ramp-up.

Metrics: up to 90% debugging time reduction · under 5-minute investigation start · company-wide adoption

“The solution reduced debugging time by up to 90%, enabled new engineers to start investigations in under 5 minutes, and has achieved company-wide adoption, fundamentally changing how engineers interact with their infrastructure.”summary, stated

Outcomes

Internal operations case across every major cloud and nearly every cloud region.
