Hi @francabral, 5 requests per second in your case here, would mean that if 6 people somehow requested data from Airtable at the exact same time, then one of them would get an error.
The likely hood of this happening is extremely low, and if you notice it happening you could implement a feature in your app to counter this, so that the data is eventually loaded.
Firebase on the other hand allows for 100 concurrent connections, so maybe this might work better for you?
