Check Aryn docset details when a table schema changes
A renamed, added, or removed column can change how you interpret a reporting workflow. Notis can retrieve metadata for the docset you identify and share it in a run report.
Trigger
Table Schema Changed
Polling trigger that detects when a table's schema changes in Google Sheets. Monitors columns added/removed/renamed and inferred type/format changes. Uses snapshot-based diffing to compare schemas between polls.
Action
Get DocSet Metadata
Tool to retrieve metadata for a specific docset. use when you have the docset id and optionally need usage statistics.
Why this helps
A table changes shape and prompts a manual review, but the related document collection status is easy to overlook.
- Pair structural sheet changes with a docset status check.
- Retrieve metadata and available usage statistics.
- Receive the result in your preferred reporting channel.
Setup
Build it in a few focused steps.
- 1Connect Google Sheets and Aryn once in the Notis portal.
- 2Create an automation in Automations, New Automation, and give it a name and prompt.
- 3In one instruction, provide the Aryn docset id and ask Notis to retrieve metadata after a table schema change.
- 4Choose the Table Schema Changed trigger, then choose where run reports go.
- 5Test with one real schema change and confirm the metadata report.
Questions about this workflow
What counts as a schema change?
The trigger monitors columns added, removed, or renamed, along with inferred type or format changes.
Does Aryn metadata explain the spreadsheet schema?
No. The action retrieves metadata for the specified Aryn docset. Interpret the sheet change using information available in the event or your instruction.
