Complex day at Fivetran

Contain AISQL answers while metric lineage stays disputed

Published Oct 22, 2026

You’re the ai / ml engineer. Your team is in the room.

The setting

's lets data teams build, transform, govern and validate their data workflows, either in a web browser or with command-line tools.

AISQL answers look credible while their metric lineage is uncertain.

Enterprise expansion protects analyst access while regulated customers require every answer to follow governed definitions.

Who you’d be doing this for

“My CFO asked where that number came from, and I had to reopen the whole project.”

Hanne Lund · Analytics Engineering Manager · a character in this brief

Leads a regulated enterprise analytics team using dbt metrics for executive reporting.

What is at stake

Plausible AISQL answers are reaching warehouses without a dependable link to approved metric definitions. You must weigh fast containment against preserving useful answers for ambiguous analyst questions.

Why it isn’t already fixed

Every obvious fix costs something else. That’s the part you’d have to decide.

  • enterprise access vs traceable metric lineage
  • fast containment vs durable runtime contracts
  • ambiguous analyst language vs deterministic tool selection
  • response latency vs verification depth

Why Fivetran

AISQL depends on dbt metric definitions and warehouse execution, so an untraceable answer weakens the governed analyst experience.

The same setting, from another role

Other problems with a similar purpose

In each of these, as in this one, the aim is to build machine-learning systems that earn trust by staying explainable where their errors carry real consequences.
