 Processing of an Initial Query Request has few extra steps comparing versus processing a regular Query Request:
 1. Query validation with `CanPaginateVisitor`. This is required to validate whether incoming query can be paged. This also activate legacy engine fallback mechanism.
-2. Creating a paged index scan with `CreatePagingTableScanBuilder` `Optimizer` rule. A Regular Query Request triggers `CreateTableScanBuilder` rule instead.
-3. `Serialization` is performed by `PlanSerializer` - it converts Physical Plan Tree into a cursor, which could be used query a next page.
