Check a ClickHouse table before working with parsed documents
Use incoming Airparser context to inspect a relevant table's structure before deciding how its data can support your work.
Trigger
Webhook received
Notis starts this workflow when an external tool or custom backend sends an HTTP request.
Action
Get Table Schema
Gets the schema and column details for a table.
Why this helps
Writing a query against an unfamiliar table can take extra back-and-forth just to confirm column names, types, and keys.
- Review a table's detailed structure before querying
- See column types and keys in the schema response
- Use a sample of table data when requested and available
Setup
Build it in a few focused steps.
- 1Connect Airparser and ClickHouse once in the Notis portal.
- 2Create an automation in Automations, New Automation, or tell Notis from any channel to create it.
- 3In one instruction, explain how the incoming parsed document context should identify a ClickHouse table for schema inspection.
- 4Choose the webhook trigger, select a report channel, and send relevant context from Airparser to the Notis webhook.
- 5Test with one real document and a known table.
