Google Sheets API Error 503: Repeated Failures with Large Spreadsheets (> 3000 Rows)

[luissantosdev]

I’m experiencing serious issues with the Google Sheets API when working with large spreadsheets containing more than 3000 rows. The API often returns the following error:

503 - {"error":{"code":503,"message":"The service is currently unavailable.","status":"UNAVAILABLE"}}

This problem is occurring several times a day across multiple requests, both for reading and writing data. On top of that, the operations are extremely slow before eventually failing, which makes the situation even more frustrating, especially for critical applications.

I’ve already reviewed my implementation to ensure there’s nothing wrong on my end, but the issue persists. It’s not an isolated case, as it consistently affects multiple spreadsheets.

Does anyone know what could be causing this? Is this a known issue with the API when handling large datasets? Are there any solutions or workarounds to mitigate this type of error?

Thank you in advance to anyone who can provide insights, but I must express my frustration—Google Sheets API is supposed to be a reliable tool for automation involving large amounts of data. This is unacceptable for a production-grade service.
