DATA OPS
Schema-Drift Remediation Agent: Quarantine, Propose Rollback, Brief Teams
On a breaking Snowflake column change, an agent quarantines the affected downstream sync, investigates root cause from the warehouse audit history.
How it runs
The automated pipeline, trigger to output.
- TriggerBreaking-change alert received
- ActionConfirm change + actor from Snowflake historySnowflake
- LogicQuarantine affected sync; reason over diff
- ActionOpen PR with rollback/migration SQLGitHub
- OutputBrief stakeholders in Microsoft TeamsMicrosoft Teams
What it does
Goes beyond alerting: an agent owns the response to a confirmed breaking schema change. It pauses the at-risk downstream sync to stop bad data from propagating, reconstructs what changed and who ran it, drafts a remediation (rollback DDL or a forward migration), opens a pull request, and posts a plain-English briefing for the team.
When to use it
When your data team is small and a breaking schema change demands containment plus a fix proposal, not just a notification. Use it where the cost of letting drift flow downstream is high and you want a first-draft remediation waiting for a human to approve.
How it works
- 1A breaking-change alert (from a detector or webhook) triggers the agent.
- 2The agent queries Snowflake history to confirm the change and identify the actor and timestamp.
- 3It pauses or flags the affected downstream sync to quarantine the blast radius.
- 4It reasons over the diff and drafts rollback or forward-migration SQL.
- 5It opens a GitHub PR containing the proposed fix and rationale.
- 6It posts a stakeholder briefing to Microsoft Teams summarizing impact, containment, and the proposed remediation awaiting review.
Set it up
What you configure once, before turning it on.
- 1Connect SnowflakeWarehouses, queries, shares.
- 2Connect GitHubRepos, issues, pull requests, actions.
- 3Connect Microsoft TeamsChannels, chats, files.
- 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.
