Saga analyzers Sagas have a powerful API, but it’s limited by the confines of C#. You can create a class that is a lousy saga but is still perfectly valid C# code. If you update your system with NServiceBus 7.7 You focus on your business logic. Let’s take a look at the new features. ?? In NServiceBus version 7.7,

(Note that “no side effects on normal execution” is always automatically true for violation handlers even when an assertion system such as proposed in [4] allows arbitrary custom violation handlers to be installed, because those are executed only if we discover that we’re in a corrupted state and so are already outside of normal execution.

When a system ‘scales’ it is able to deliver higher levels of performance proportional to the system resources available to it. In particular, this means as we add CPU cores and increase the system load, we see higher performance. In this example, we will compare MySQL 5.7.33 and MySQL 8.0.25 and MySQL 5.7.33.

Therefore, before we attempt to measure our database performance, we should know the system or cloud instance to be tested in detail. Operating System: Ubuntu 22.04 Database: MySQL 8.0.31

If we accept the fact that Agile is a value system and not a set of mechanical processes, it stands to reason that there must be something different about the norms and behaviors of Agile managers vis-a-vis traditional managers.
