Look up ClickHouse table structure from an assigned issue
When an assigned issue asks how a specific ClickHouse table is structured, Notis can retrieve its schema so you can plan the query without opening another tool.
Trigger
New Issue Assigned to Me
Triggers when a new issue is assigned to the authenticated user. Fires an event for each GitHub issue that is newly assigned to the authenticated user. Pull requests are automatically excluded -- only true issues are emitted. Issues can optionally be filtered by labels and state. The payload includes the issue number, title, body, state, labels, assignees, creator, repository details, and timestamps.
Action
Get Table Schema
Get detailed schema information for a specific table including column definitions, types, keys, and optionally sample data. this is essential for ai agents to understand table structure before constructing queries.
Why this helps
Query work stalls when the relevant column names and types are hidden behind a separate schema lookup.
- See the named table’s columns and types in the context of the assigned work.
- Avoid returning sample data when the task only needs structural details.
Setup
Build it in a few focused steps.
- 1Connect GitHub and ClickHouse to Notis once in the portal.
- 2Create the automation in the portal or ask Notis for it in plain language.
- 3Tell Notis to retrieve schema only when an assigned issue explicitly names a ClickHouse database and table, and not to include sample rows.
- 4Select GitHub New Issue Assigned to Me and choose where run reports should go.
- 5Test with one assigned issue that names an existing database and table.
Questions about this workflow
Does it run a query against the table?
No. This workflow retrieves the table schema, including column definitions and types, and does not execute SQL.
Does it return sample rows?
No. The instruction requests structural details only and excludes optional sample data.

Supported Triggers and Actions
Notis builds workflows that link GitHub to ClickHouse. A trigger fires from one place; an action lands in another.
GitHub triggers
ClickHouse actions
Recurring trigger
Notis starts this workflow on a schedule, such as daily, weekly, or during business hours.
Execute ClickHouse Query
Execute a sql query in clickhouse and return the results. this is the primary action for querying data from clickhouse databases.
Webhook trigger
Notis starts this workflow when an external tool or custom backend sends an HTTP request.
Get Database Schema
Get comprehensive schema overview of an entire database including all tables and optionally their column definitions. essential for ai agents to understand the complete database structure in a single call.
New Workflow Artifact Created
Triggers when a new workflow artifact is created in a GitHub repository. Monitors for newly created GitHub Actions workflow artifacts. Optionally filters by artifact name to restrict monitoring to specific artifacts.
Get Table Schema
Get detailed schema information for a specific table including column definitions, types, keys, and optionally sample data. this is essential for ai agents to understand table structure before constructing queries.
Branch Changed
Triggers when a GitHub branch changes. Monitors a specific branch for: - New commits pushed (head commit SHA changes) - Protection status toggled (branch becomes protected or unprotected) - Protection settings changed, including: required status checks and their enforcement level, admin enforcement, required pull request reviews (dismiss stale reviews, code owner reviews, approving review count, last push approval), required linear history, force push allowance, deletion allowance, conversation resolution, branch locking, and fork syncing.
List ClickHouse Databases
List all databases in the clickhouse instance. useful for discovering available databases before querying tables.
New Branch Created
Triggers when a new branch is created in a GitHub repository. Detects newly created branches. Deleted branches do not fire events.
List ClickHouse Tables
List tables in clickhouse databases. returns information about tables including their engine, size, and row count.
Check Run Status / Conclusion Changed
Triggers when a specific GitHub check run changes its status or conclusion. Monitors a single check run for changes to: status (queued, in_progress, completed, etc.), conclusion (success, failure, neutral, cancelled, skipped, timed_out, action_required), started_at, and completed_at.
Check Suite Status / Conclusion Changed
Triggers when a GitHub check suite changes its status or conclusion for a given ref. Monitors all check suites associated with a git reference (branch, tag, or commit SHA) for changes to status (queued, in_progress, completed, etc.) and conclusion (success, failure, neutral, cancelled, skipped, timed_out, action_required, startup_failure, stale). Optionally filters by GitHub App ID.
New Code Scanning Alert Created
Triggers when a new code scanning alert is created in a repository. Fires an event for each newly created code scanning alert detected in the configured repository. Alerts can be filtered by Git reference, scanning tool, state, and severity. The payload includes the alert number, rule details, tool information, state, severity, and the location of the most recent instance.
