Is the pagination preview feature that was announced here Looker release notes | Google Cloud Documentation client side pagination or server side pagination? If it is server side pagination then I assume row limits would no longer be an issue and users can see the entire result set (a page at a time) if they want to. But if it is client side pagination I assume row limits would still be an issue and this feature only really serves to change the size of the table visually speaking.
So which is it, server side pagination or client side pagination?
