Check ClickHouse when a Drive file matches
A matching Drive file can trigger a focused lookup in your ClickHouse data.
Trigger
New File Matching Query
Triggers when a new Google Drive file matches a provided query. This is the legacy query-centric trigger: it preserves Drive API query config such as ``corpora`` / ``driveId`` aliases and emits the historical ``file_matching_query`` event type. ``FileCreatedTrigger`` covers the broader "new file" case and emits ``file_created``.
Action
Execute ClickHouse Query
Execute a sql query in clickhouse and return the results. this is the primary action for querying data from clickhouse databases.
Why this helps
When a specific file arrives, the related numbers or records may require a separate manual search.
- Start a focused data lookup from a matching file event.
- Bring relevant ClickHouse results into the automation report.
- Use your existing query and business context.
Setup
Build it in a few focused steps.
- 1Connect Google Drive and ClickHouse once in the Notis portal.
- 2Create an automation in Automations with a name, prompt, report channel, and trigger.
- 3Tell Notis which ClickHouse query to run for a matching file; provide the query logic and any table or column details it needs.
- 4Choose the New File Matching Query trigger and where run reports should go.
- 5Test with one real file that matches your Drive query.
Questions about this workflow
How does the Drive matching work?
This legacy query-centric trigger fires when a new Drive file matches a query you provide, including supported Drive query configuration.
Can ClickHouse query the file contents?
Only if the needed content or a reference to it is available to the automation and your ClickHouse data/query supports that lookup. The trigger alone does not promise file-content extraction.

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.
Comment Added (Docs/Sheets/Slides)
Triggers when a new comment is added to Google Docs, Sheets, or Slides.
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.
File Created
Triggers when a new file is created in Google Drive.
List ClickHouse Databases
List all databases in the clickhouse instance. useful for discovering available databases before querying tables.
File Deleted or Trashed
Triggers when a file is moved to trash or permanently deleted in Drive.
List ClickHouse Tables
List tables in clickhouse databases. returns information about tables including their engine, size, and row count.
File Shared (Permissions Added)
Triggers when new sharing permissions are granted to a file or folder. Uses Drive's `changes.list` endpoint with inline `permissions` in the `fields` mask so each change carries the file's current permission set provider-atomically. We diff that against `seen_permission_keys` to identify newly added grants. Drive page tokens are the primary cursor; if Drive rejects a stored token, the trigger raises `PollingTriggerError` without clearing state rather than silently re-baselining and dropping events. Limitation: truly ephemeral permissions (added and revoked between two polls without any other file modification in between) are not detected. Drive Activity API would catch those but requires an additional OAuth scope and a different payload contract.
File Updated
Triggers when a file's metadata or content changes in Google Drive.
Google Drive Changes
Triggers when changes are detected in a Google Drive.
