Managing Concurrent Updates

Hi! Recently, I was asked how to manage transactions against databases in this multithread world.

So, I have spent my time in the last week studying some solutions. I start, understanding about Optimistic Locking and Pessimistic Locking. Here is a great article to do that: https://www.baeldung.com/jpa-pessimistic-locking

Tech

I used a number of open source projects to work properly:

• [SpringBoot]
• [JUnit]
• [H2]
• [Hibernate]

Running

Run the IntegrationTest! Run the IntegrationEtagsTest!

Enjoy it!
