This time, we've got some exciting news to share with you! Persisting a collection like List in JPA is attained in two following ways, 1. ElementCollection annotation - specifying CollectionTable annotation with the column onto which the OneToMany relationship has to be established  2. AttributeConverter Implementation - override the convertToDatabaseColumn and convertToEntityAttribute for persisting and retrieval of the collection

This time, we've got some exciting news to share with you! ZGC optimizes the HotStop JVM GC for low latency and scalability, offering the benefits of, 1. Scalable Heap memory area  2. Low latency <1ms GC pause times regardless of the heap size definitions 3. Autotuned GC for optimal performance  4. Throughput reduction  As the ZGC is designed, 1. Concurrency - threads continue to execute and collect objects for GC  2. Constant GC

The REST requests are to be intercepted for carrying out preprocessing not only on the URL but on the whole request before delegation to the controller. Create an implementation for ClientHttpRequestInterceptor and override the intercept method, subsequently registering the interceptor onto the rest template, any requests are routed via the implementation. https://www.baeldung.com/spring-restt

The Chronicle library facilitates creating the memory region of the heap on a file for virtual memory and debugging the file with readable YAML format. The feature of the memory map file has been available since JDK4, FileChannel.map + MapMode.READ_WRITE = MappedByteBuffer (not thread safe) Other places for improvement are, 1) Thread safe access 2) Long offsets (64-bit) 3) Comple

It used JDK 17 as a baseline, and Jakarta EE 9+ with specifications for Servlet 6.0 and JPA 3.1 facilitating access to Tomcat 10.1 and Hibernate ORM 6.1 respectively. Spring application contexts support AOT transformation processing as part of GraalVM Native image used in tandem with Spring Boot 3. Spring 6.0 enables the usage of Project Loom's Virtual threads feature and Project CRaC with checkpoint restoration for faster JVM startup and many other features. https://spring.io/blog/2022/11/16/spring-framework-6-0-goes-ga Establishing a good degree of isolation can vary regarding deployment (Microservices) or DDD-bounded context.
