When is Transaction getting committed when using @Transactional

I have a spring boot service class method which is annotated with @Transactional, where I will need to commit the transaction to MYSQL DB and then execute the finally block of code which is to push the entity to a Redis queue. Below is my code snippet:

@Transactional
public void save(Entity t) {
    try {
         entityRepository.save(t);
    } catch(Exception ex) {
         log.error("Error while executing transaction",e);
    } finally {
        //code to push to redis
    }
}

My doubt is whether the transaction will be committed and the finally block will be executed? Or the @Transactional will complete all the transaction only after the finally block completes. If it is the latter, how do I ensure that my transaction is committed before pushing to Redis?

Please advice.

NOTE: entityRepository is a class which extends CrudRepository

The transaction will be commited only after the finally block.

For the use case mentioned look at: Creating a post commit when using transaction in Spring

Register a TransactionSynchronization with an afterCommit or afterCompletion.
