In theory, no there is no hard row limit that is currently enforced in google sheets or glide tables, but you have to consider the amount of data that’s synced between google sheets > glide servers > user’s device. Glide tables won’t make any difference for the sync between glide servers and the device, but it does remove the bottleneck between glide servers and google sheets. A lot of data means a lot to sync. Regardless, the sync between glide and google should be transparent to the user as long as there are no formulas in the Google sheet and all calculations are performed using glide functionality.
If you are using Row Owners, you can reduce the amount of data that’s synced to the user’s device and not overload the user with too much data. This is what truly provides you with the theoretical “no row limit”.
