To fight inequalities in access to education, Learni donates a complete school kit to a child in need for every training booked. You build your skills, a child heads back to school.
Founded by engineers and learning experts, Learni's mission is to make high-impact tech training accessible to teams everywhere. We work remotely with organizations across the US and Canada, in your time zone, to help teams upskill fast.
Don't let this gap widen
Without this upskilling, your team accumulates a technological gap that translates directly into productivity loss.
Organizations that don't train their talents on key topics see their competitiveness drop.
Every quarter without training is a gap widening with competitors who invest.
The cost of inaction quickly exceeds that of well-targeted training.
Discover advanced JPA mapping techniques with Hibernate, modeling inherited entities, bidirectional relationships, and lazy loading through practical exercises on a real e-commerce case. Configure @Embedded and @ElementCollection annotations, generate an optimized ER schema, and test mappings in an H2 database to validate persistence without errors.
Dive into expert JPQL with multiple joins, subqueries, and aggregates, then move to Criteria API for dynamic queries secured against SQL injection. Apply to a banking project with millions of records, optimize using fetch joins and pagination, generate performant reports, and analyze execution plans for up to 50% speed gains.
Configure L1 and L2 caches in JPA/Hibernate to minimize database accesses, test invalidations and Ehcache clusters, integrate into high-traffic applications, measure hits/misses with JMX, adjust TTL and sizing policies, develop stress-testing exercises, and achieve up to 70% latency reductions in simulated production.
Implement advanced JPA locking modes to manage concurrency, simulate deadlocks and resolutions using SELECT FOR UPDATE, integrate @Version for optimistic locking, apply to distributed microservices with Spring, test sagas for long-running transactions, produce audit logs, and secure critical enterprise operations.
Integrate JPA into Spring Boot with custom Data JPA repositories, configure multi-datasources and Flyway migrations, deploy on Docker/K8s, monitor via Actuator and Micrometer, review security audits and best practices, finalize a complete e-commerce microservices project, and obtain a deployable deliverable with professional skills certification.
The JPA Training - Mastering Advanced Enterprise Persistence program is delivered onsite or remote (blended-learning, virtual classroom, remote presence). At Learni, an industry-certified training organization, every program is built to maximize skills acquisition regardless of the chosen format.
The trainer alternates between demonstrative, interrogative and active methods (through hands-on labs and/or scenarios). This pedagogical approach guarantees concrete learning that's immediately applicable at work.

Before, during, after: we frame the brief, introduce the trainer, tailor the content and measure impact. You stay in control from kickoff to wrap-up.
Each trainer is validated on three criteria: hands-on field expertise, proven pedagogy and alignment with your industry.
30-minute video call between you and the selected trainer to validate the fit, adjust content and clear any final doubts.
No recycled slides. The syllabus is reworked from your real cases: tools, constraints, vocabulary, ongoing projects.
Live evaluations, 30/90/180-day check-ins and a consolidation plan. If the impact misses the mark, we rework it.
A simple promise: you don't pay to discover the trainer on day one. Everything is validated upfront, by you.
