Hi, we are using Embeded objectDB 2.4.4_06 in a highly multithreaded concurrent manner and we have noticed a performance problem in our application that seems to be attributed to ObjectDb's internal locking. When profiling our app in JVisualVm we notice a large number of threads are blocked

We are testing objectDB with a multi thread application . Each thread has it's own entityManager created from a common factory. In one thread we receive sometimes an object from the database with the field that is declared as @Id having the value null (what is not correct, we checked

ObjectDB requires Java 8 or later. As a pure Java application , ObjectDB should be able to run on any platform that supports the Java Standard Edition. Either the Java Development Kit (JDK) or the Java Runtime Environment (JRE) can be used. A version of ObjectDB for .NET is currently under development.

Jakarta Persistence (JPA) provides a set of annotations to define and map native SQL queries when the standard Java Persistence Query Language (JPQL) is insufficient. While ObjectDB focuses on JPQL and ignores these annotations, they remain essential for applications interacting with relational

An entity class is a user-defined class whose instances can be stored in a database. To store data in an ObjectDB database using Jakarta Persistence (JPA), you define entity classes that represent your application's data object model. This chapter contains the following sections:

Jakarta Persistence (JPA) defines a hierarchy of unchecked exceptions rooted in PersistenceException to handle runtime failures. This structure enables applications to catch specific errors or manage broad persistence issues by using the base class. The exception hierarchy is as follows
