While reading??  Can you post the error message?

These errors typically mean that your app is triggering too many queries against the Google sheet within a period of time.   Usually the issue is the usage of sheet-side formulas that cause cascading updates that lead to many queries executing in attempts to update all data.  AppSheet will wait for the sheet updates to complete before reading a fresh set of data to load into the app.

I hope this helps!

The "Google Drive Rate Limiting Exception while reading" error in AppSheet means that AppSheet is making too many read requests to Google Drive in a short period, and Google temporarily blocks further access to avoid server overload.

 

Here are some practical steps to resolve and prevent this:

 

Immediate Fixes:

 

1. Wait and Retry:

 

Rate limits are usually temporary. Wait 5โ€“15 minutes and try reloading the app again.

 

 

 

2. Reduce Simultaneous Edits:

 

If multiple users or apps are accessing/editing the same Google Sheet or file, it can trigger rate limits. Ask users to pause activity temporarily.

 

 

 

3. Check Sheet File Size and Complexity:

 

Very large or complex sheets with many formulas, tabs, or data validations can slow things down and increase the chance of hitting rate limits.

 

 

Prevent Future Rate Limiting:

 

1. Split Large Sheets:

 

Divide a large Google Sheet into multiple smaller ones if possible. Link them in AppSheet via different tables.

 

 

 

2. Use Security Filters and Slices:

 

Filter data on load so that only necessary records are read. This reduces the volume of data read from Drive.

 

 

 

3. Minimize Virtual Columns:

 

Too many virtual columns (especially with complex formulas) can cause AppSheet to frequently re-read and recalculate data, increasing read pressure.

 

 

 

4. Avoid Real-time Syncing:

 

Turn off โ€œSync on Startโ€ and โ€œDelayed Syncโ€ if your app doesnโ€™t need live updates constantly.

 

 

 

5. Enable โ€œDelta Syncโ€ and โ€œServer Cachingโ€:

 

In Behavior > Offline/Sync, enable:

 

Delta Sync

 

Server caching

 

These reduce the amount of data AppSheet reads each time.

 

 

6. Use Google Cloud Storage or SQL:

 

If your app grows too big, consider moving your backend from Google Sheets to Google Cloud SQL or Cloud Storage for better performance and higher rate limits.

 

Would you like help checking your AppSheet settings or optimizing your sheets to prevent this error? You can share details like table size, number of users, or whether real-time updates are necessary.
