@Transaction Around Test

Hi, My fingers were tingling at the start of Thorben Janssen’s session “The Big Java Persistence Q&A”. The first question was roughly: “In the previous talk (something with JPA), it was said that one should annotate every test with @Transactional. This will automatically roll back the data after the test. We’ve had a discussion and can’t agree. What’s your recommendation?” Thorben’s answer made me nervous. He countered with a question of his own, also paraphrased:

Panic

Hi, Nervousness sliced through the room. I saw it in the eyes of all attendees. It was supposed to be just a routine meeting. Once a week, the development team meets with the admins to discuss current topics. This meeting has been held for years. Same time, same people, (almost) the same topics. But something was different this time. A new colleague participated for the first time. An external. We brought him in to work on “DevOps”.

Is Scrum Democratic?

Hi, Is Scrum democratic? This question keeps coming up. Time and time again, I find myself in teams where this question becomes the focal point.

The Product Owner decides which tasks are to be tackled and in which order. And he is a part of the team.

Redundant Information

Hi, “After importing, we unpack the file and read the meta-information.” “And where do we write it?” “This information is stored in different databases. The path information is distributed across all service databases so that they know how to access the files. Other data is stored in the system database and in each tenant database.” Does that sound normal to you? It shouldn’t. What we are experiencing here is information duplication.
