Hibernate ORM and RHEL-hosted Databases: Keyset Pagination vs Offset-based Interoperability

Implementing pagination for large datasets requires a choice between standard JPA offset methods and keyset pagination to maintain performance on Red Hat Enterprise Linux (RHEL) hosted database environments.
Using setFirstResult() and setMaxResults() triggers the Hibernate Dialect to generate LIMIT and OFFSET clauses. While this is the standard interoperability path, high offset values force the underlying database to scan and discard a significant number of rows, potentially increasing CPU and I/O load on the RHEL host.
Keyset pagination (the seek method) avoids this scan by filtering on a unique identifier from the previous page, but it requires a different query structure than the standard JPA pagination API.
- How does the choice of Hibernate Dialect on RHEL impact the translation of keyset pagination logic into optimized SQL?
- What are the trade-offs in database resource consumption when switching from offset-based to keyset pagination for deep-page queries?
