DATA OPS
Route Schema-Change Webhooks to the Right dbt Owner by Severity
Receives a schema-change webhook from your ingestion tool, traces which dbt models depend on the changed table.
How it runs
The automated pipeline, trigger to output.
- TriggerWebhook receives schema-change eventHTTP webhook
- ActionMap changed table to dependent dbt models and owners
- LogicGrade severity: breaking vs additive
- OutputPage on-call via PagerDuty for breaking changesPagerDuty
- OutputPost low-key Slack note for additive changesSlack
What it does
Accepts a real-time webhook fired by your data-ingestion connector when it detects an upstream schema change. It maps the changed table to dependent dbt models, scores the change's severity, and routes the alert to the right place: an urgent page for breaking changes, a low-key Slack message for harmless additions.
When to use it
Use it when your loader (Fivetran, Airbyte, or similar) already emits schema-change events and you want push-based, severity-aware routing instead of polling. Ideal for teams that page on-call only for changes that can actually break a build.
How it works
- 1An HTTP webhook receives the schema-change event from the ingestion tool.
- 2The payload is normalized and the changed table is matched to its dependent dbt models and owners.
- 3A logic step grades severity: dropped or retyped columns are breaking, new nullable columns are additive.
- 4Breaking changes trigger a PagerDuty incident routed to the owning team's on-call.
- 5Additive changes post a non-urgent Slack note to the team channel for awareness only.
Set it up
What you configure once, before turning it on.
- 1Connect HTTP webhookTrigger any URL on agent actions.
- 2Connect PagerDutyIncidents, on-call, escalations.
- 3Connect SlackChannels, DMs, threads, mentions.
- 4Set each agent's modelWe leave models unset so you pick the tier — fast + cheap, or top-quality.
- 5Tune it to your dataEdit the prompts, filters, and field mappings so it matches how your team works.
- 6Test, then turn it onRun once against a sample, confirm the output, then enable the trigger.
