Automatically track Notion schema changes in BigQuery
Schema changes in Notion break queries and confuse downstream work. Notis logs every column add, remove, and rename to BigQuery so you catch changes before they cause problems.
Trigger
Data Source Schema Updated
Fires when a data source’s columns are added, removed, or renamed.
Action
Query
Runs a SQL query in BigQuery, including statements that can modify data.
Why this helps
Notion schema changes (adding columns, renaming fields) silently break BigQuery queries. There's no audit trail of when columns were added or removed, so debugging is a guessing game.
- Catch schema changes immediately before they break queries
- Build schema change alerts and notifications
- Track column lifecycle (creation, renames, deletion) for compliance
- Automate downstream impact analysis by querying schema change history
Setup
Build it in a few focused steps.
- 1Connect Notion workspace to Notis.
- 2Connect Google BigQuery to Notis.
- 3Ask Notis: 'When a Notion data source schema is updated, log the data source ID, updated column names, action type (add/remove/rename), timestamp, and editor email to BigQuery.'
- 4Select 'Data Source Schema Updated' as the trigger.
- 5Pick your reporting channel.
- 6Test by adding or renaming a column in a Notion data source and confirming the record in BigQuery.
Questions about this workflow
Will this log single column changes or batch updates?
Both. Notis receives the schema update event which includes all changed properties, and logs them as detailed records.
Does adding a column fire other events too?
Yes. Adding a column also fires 'Page Properties Updated' once per existing row. Use 'Data Source Schema Updated' for a single structural-change signal.
Can I filter to specific data sources?
Yes. Notis can scope the trigger to log schema changes only for certain data sources.
