How does JTA transaction work?

What is XA transaction?

XA is a two-phase commit protocol that is natively supported by many databases and transaction monitors. It ensures data integrity by coordinating single transactions accessing multiple relational databases.

What is Bitronix transaction manager?

Bitronix Transaction Manager is a standalone implementation of JTA. Spring is a framework that provides (among other features) unified interface for transaction management. In particular, Spring-managed transaction can use JTA implementation as a backend.

How does Spring Boot manage transactions?

Instead, you now need to do two things:

  1. Make sure that your Spring Configuration is annotated with the @EnableTransactionManagement annotation (In Spring Boot this will be done automatically for you).
  2. Make sure you specify a transaction manager in your Spring Configuration (this you need to do anyway).

What is JTA and JPA?

What is JTA in WebLogic?

What is XA and non-XA transactions?

An XA transaction involves a coordinating transaction manager, with one or more resources (databases\JMS) all involved in a single global transaction. Non-XA transactions have no transaction coordinator, and a single resource is doing all its transaction work itself (also called local transactions).

Does Kafka support XA?

Any attempt to involve any third-party data sources in the business process is stuck because the Kafka fundamentally does not support XA transactions.

What is JPA and JTA in Java?

Which spring Transactionmanager do you use when creating XA transactions?

Spring Boot supports distributed JTA transactions across multiple XA resources by using either an Atomikos or Bitronix embedded transaction manager. JTA transactions are also supported when deploying to a suitable Java EE Application Server.
