Find available ClickHouse databases when a Box file changes
A file's name, parent folder, or other metadata changes can prompt a review. Notis can list ClickHouse databases so you can orient the follow-up.
Trigger
File Metadata Changed
Triggers when a file's metadata or properties change in Box. This trigger monitors a specific Box file and fires when changes are detected in key fields like name, description, size, modification time, parent folder, or status.
Action
List ClickHouse Databases
List all databases in the clickhouse instance. useful for discovering available databases before querying tables.
Why this helps
A renamed or moved file can leave you unsure which analytics environment to check next.
- Get a current list of available databases after a file metadata event.
- Keep discovery results attached to a run report for later review.
- Avoid searching through the ClickHouse interface just to find available databases.
Setup
Build it in a few focused steps.
- 1Connect Box and ClickHouse once in the Notis portal.
- 2Create an automation in Automations, New Automation, and name it for database discovery.
- 3In one instruction, tell Notis to list ClickHouse databases and explain how the list should inform your file review.
- 4Pick Box's File Metadata Changed trigger and select the file to monitor.
- 5Choose a report channel, then test with one real metadata change and review the database list.
Questions about this workflow
Does listing databases tell me which one contains data for the file?
No. The action lists databases. A relationship between a Box file and a database must be supplied or established using other available context.
Can the workflow query a database too?
This workflow uses the database listing action. A separate query action can be used when you specify the query and relevant database context.
