Hey!

Today, we go back to the fundamental Modularity topics, but with a data/state-heavy focus, delving into things like:

• local vs global data consistency scope & why true transactions are possible only in the first one
• immediate vs eventual consistency & why the first one is achievable only within local, single module/service scope
• transactions vs long-running-processes & why it is not a good idea to pursue distributed transactions - we should rather design and think about such cases as processes (long-running) instead
• Sagas, Choreography and Orchestration

Here is the deep dive: https://binaryigor.com/data-consistency-transactions-delays-processes.html

Hope you find it fascinating and see you in the next entry!
