JTA Transaction Type
Introduction In this article, we are going to analyze how the JTA transaction type works. Since this is the default transaction type when using Jakarta EE or Java EE applications, it’s very important to understand how JTA transactions work, especially since Spring Boot or Spring applications use RESOURCE_LOCAL transactions instead.
How does aggressive connection release work in Hibernate
Hibernate connection providers Hibernate needs to operate both in Java EE and stand-alone environments, and the database connectivity configuration can be done either declaratively or programmatically. To accommodate JDBC Driver connections as well as RESOURCE_LOCAL and JTA DataSource configurations, Hibernate defines its own connection factory abstraction, represented by the org.hibernate.engine.jdbc.connections.spi.ConnectionProvider interface.
How does Hibernate TRANSACTIONAL CacheConcurrencyStrategy work
Introduction In my previous post, I introduced the READ_WRITE second-level cache concurrency mechanism. In this article, I am going to continue this topic with the TRANSACTIONAL strategy.
A beginner’s guide to transaction isolation levels in enterprise Java
Introduction A relational database strong consistency model is based on ACID transaction properties. In this post we are going to unravel the reasons behind using different transaction isolation levels and various configuration patterns for both resource local and JTA transactions. Isolation and consistency In a relational database system, atomicity and durability are strict properties, while consistency and isolation are more or less configurable. We cannot even separate consistency from isolation as these two properties are always related. The lower the isolation level, the less consistent the system will get. From the least… Read More
