Learn how to prevent Hibernate from performing in-memory pagination, which causes OutOfMemoryErrors, by implementing a two-step ID retrieval pattern.
Stop the performance decay of large datasets. Learn why Hibernate's setFirstResult can crash your app and how to implement Keyset Pagination for constant-time data retrieval.
Learn how Hibernate’s query cache and pagination can cut database load for repeatable queries, and what trade‑offs to watch before enabling them in your Java service.
Learn how to replace costly offset pagination in Hibernate with cursor‑based streaming that eliminates count queries and keeps memory usage constant.
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
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
Hibernate Pagination Limits with Join Fetching Hibernate exposes pagination through setFirstResult() and setMaxResults() on the Query interface. The generated SQL is dialect-dependent, using LIMIT/OFFSET or window functions according to the configured Database Dialect. A documented constraint appears when those methods are combined with JOIN FETCH on collect
I don't see the "hibernation after X minutes" option in my Windows 11. On other computers I had, there was an option in Control Pane > Power Options > Change plan settings > Change advanced power settings . There i could set the time after which the computer should go into hibernation. Note that: I have hibernation enabled and can see it in the Star
When managing large datasets in Hibernate, the setFirstResult and setMaxResults methods are used to bound queries and implement pagination by translating these calls into dialect-specific LIMIT and OFFSET clauses. A primary concern arises when navigating deep into a result set. As the start position increases, the database must scan and discard a growing num
