People can lose time searching for datasets or asking colleagues whether a table exists.
- Makes table discovery available at the point of need.
- Reduces repeated questions about what datasets exist.
- Provides a clear starting point for later schema or query work.
Setup
Build it in a few focused steps.
- 1Connect Slack and ClickHouse to Notis once through the portal.
- 2Create the automation in the portal, or explain the workflow to Notis conversationally.
- 3Use one instruction asking Notis to list ClickHouse tables for the relevant database when a channel message asks what tables are available.
- 4Choose Channel Message Received as the trigger and select a channel for run reports.
- 5Test with one real table-discovery request and check that the inventory is scoped appropriately.
Questions about this workflow
Can it list tables across the instance?
The ClickHouse action lists tables in databases. State in the prompt whether Notis should focus on a named database or provide a broader inventory.
Does the workflow explain table contents?
A table listing is an inventory. Use a schema lookup for column-level detail or a query for data results.
