Why this helps
Finding the right starting place for a data question can feel like a larger task than the question itself.
- Provides a low-friction starting point for private questions.
- Returns more context than a database-name list alone.
- Keeps discovery details with the original DM.
Setup
Build it in a few focused steps.
- 1Connect Slack and ClickHouse to Notis once through the portal.
- 2Create an automation in the portal, or tell Notis what you want in a conversational channel.
- 3Give Notis one instruction to retrieve a ClickHouse database schema overview when a DM asks what data is available and summarize the useful starting points.
- 4Select Direct Message Received as the trigger and choose a channel for run reports.
- 5Test with a real DM asking for a data overview and review the response for clarity.
Questions about this workflow
Does this return every column?
The schema overview can include column definitions. Ask Notis for a compact summary and a more detailed follow-up only when needed.
Will it query customer data?
The schema action describes database structure; it does not run an analytics query over the data.
