Why this helps
Uncertainty about which database contains relevant data can stall an investigation before it begins.
- Answers a basic discovery question at the point it comes up.
- Helps direct later table and schema lookups.
- Cuts down on repeated requests for access or orientation.
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 describe it to Notis conversationally.
- 3Use one instruction asking Notis to list available ClickHouse databases when a channel message asks what databases exist.
- 4Select Channel Message Received as the trigger and choose a channel for run reports.
- 5Test with a real database-discovery request and review the returned list.
Questions about this workflow
Does this show table details too?
No. It lists databases. Use a table-list or schema workflow for more detail.
Can Notis recommend which database to use?
It can report the available names, but the prompt should not ask it to infer a database's purpose without supporting context.
