Hi Eunsu, Unfortunately there is not really a way to do this that I'm aware of. The page id contains data indicating where to start reading the next set of rows (such as partition and clustering information), and in order to get to that position you have to actually read the data.
The driver does have an API for manually specifying the page id to use and we've documented some strategies <https://docs.datastax.com/en/developer/java-driver/3.3/manual/paging/#saving-and-reusing-the-paging-state> for storing and reusing the page id later, but not sure if that helps for your particular use case.
