javaEfficient Hibernate Pagination with Cursor-Based Techniques
Learn how to replace costly offset pagination in Hibernate with cursor‑based streaming that eliminates count queries and keeps memory usage constant.
xdHibernate validate mode and online schema changes during zero-downtime migration
Assuming Hibernate 6.x, the goal is to deploy an application update without downtime while an external migration tool applies compatible schema changes. Hibernate is configured with hibernate.hbm2ddl.auto=validate so it does not generate DDL. Documented guidance treats automatic schema generation as a development-time feature and points to external tools for
Statistics is not enabled: Hibernate Statistics API access error
Statistics is not enabled The Hibernate ORM throws a org.hibernate.HibernateException with the message "Statistics is not enabled" when SessionFactory.getStatistics() is called while statistics collection is not explicitly activated. This behavior is documented in the Hibernate 5.x and 6.x APIs and is triggered only by accessing the statistics API, not by ot
Is there a rule that forbids to name its entity class "User" when working with PostgreSQL and Spring Boot?
guys. I'm having a problem with a Spring boot 2.3.0 and PostgreSQL 12 project. I have an entity class I called User whose code is as follows: @Entity @NoArgsConstructor @Data @AllArgsConstructor @Builder public class User { @Id @GeneratedValue(strategy = GenerationType.IDENTITY) private Long id; private String username; private String email; private String f
Hibernate ORM pagination with PostgreSQL: ensuring idempotent retries for offset-based queries
Goal: guarantee that a transient failure during a paginated Hibernate query does not cause duplicate or missing rows when the request is retried with the same offset and limit. Constraint: Hibernate translates setFirstResult() and setMaxResults() to database‑specific LIMIT/OFFSET clauses, which rely on the current ordering of rows. If the underlying data cha
Hibernate Pagination: Transitioning from Offset to Keyset for Resource Optimization
Optimizing Low-Traffic Workloads When managing resource consumption for low-traffic workloads in Hibernate, the choice of pagination strategy directly impacts database CPU and memory overhead. The standard setFirstResult() and setMaxResults() approach relies on offset-based pagination, which requires the database to scan and discard rows as the offset increa
Managing Hibernate schema migrations during Scalingo rolling updates
Scalingo implements zero-downtime deployments through rolling updates, where new containers are spun up and health-checked before the previous version is terminated. This mechanism ensures continuous traffic flow via the platform's load balancer. When deploying Java applications using Hibernate ORM, there is a potential conflict between the rolling update pr
