> Currently, we do not expose the page header metadata and they cannot be used for skipping pages. I propose exposing the metadata through a callback that would allow the caller to decide if they want to read or skip the page based on the metadata. The signature of the callback would be the following: std::function<bool(const format::PageHeader&)> skip_page_callback)
