Ship data changes without flying blind
Typedef gives platform and data engineers end-to-end blast radius, root cause tracing, and automated fix plans across online, streaming, and offline systems.
Every PR is a gamble
You rename a column, refactor a model, or swap a source and hope nothing downstream breaks. Typedef computes the full blast radius before you merge, showing exactly which dashboards, metrics, and pipelines are affected.
Pipelines fail, context doesn’t exist
When a nightly job fails, the on-call engineer digs through logs, DAG views, and Slack threads. Typedef traces the upstream change that caused the failure, maps every affected model, and generates a ready‑to‑execute fix plan: files, steps, and verification queries.
Lineage stops at system boundaries
Your dbt lineage doesn’t know about Salesforce. Your warehouse lineage doesn’t know about Kafka. Typedef builds one graph across systems of record, streaming infrastructure, and offline analytics so lineage doesn’t break at handoff points.
How it plays out
PR to Dashboard
Scenario
A product engineer opens a PR touching a model. Typedef computes the downstream dashboards and metrics affected before merge, so teams understand blast radius early.
TYPEDEF ACTIONS
Detects the changed model and its position in the Data Context Layer
Computes every downstream dependency: dashboards, metrics, pipelines, and consumers
Surfaces the blast radius in the PR before merge
Shows which teams own the affected assets, so engineers can notify proactively
Output
Root Cause + Plan
Scenario
A nightly pipeline fails. The on-call engineer gets paged.
TYPEDEF ACTIONS
Identifies the upstream change that triggered the failure (schema change, source swap, definition update)
Maps all affected models downstream of the root cause
Surfaces the blast radius in the PR before merge
Generates a fix plan: which files to edit, in what order, with verification queries to confirm the fix
