Does it clone the data? We have a table with 35GB data, what happen in that case?

Their website says they clone at 6s/TB so you probably will get a branch less than 1s

Does it make it remotely? I mean, you can do that locally with

``` CREATE DATABASE cloned_db WITH TEMPLATE source_db OWNER your_owner; ```

It does clone the data. It uses copy on write to clone so data size won't slow it down since it's a metadata operation instead of actual data movement

It clones the entire DB so it's not quite 6s per TB but actually the entire thing takes <6s independent of size

Probably something to adjust on the site to make it clearer!
